A Story From the Field: Good News From the NICU, and a Big Question

Praew and Phum are first-time parents. They live in a single-storey detached house in a housing estate off Chalong Krung Road in Lat Krabang. Their first daughter, nicknamed Khao Hom, was born several weeks early and spent almost two months in the neonatal intensive care unit. Every day the couple took turns visiting, delivering expressed breast milk, and counting down the days until she could come home.

Then the 2026 floods arrived. Water from the canals and the low fields around the estate flowed into the house, reaching roughly mid-shin, and stayed for nearly a week. The room they had prepared as a nursery months before the birth was flooded too. They had painted it, hung curtains printed with little stars, and set up a cot. A foam play mat and boxes of baby clothes that had been stacked on the floor were soaked through.

When the water went down, Phum came back to open the house. A damp, musty smell mixed with mud hit him immediately. The nursery walls showed a clear tide line, and below it small black spots of mold had started to appear on the freshly painted surface. The cot's particle-board legs had swollen, and the star-print curtains had mold spots along the hem. A few days later, the NICU nurse called with wonderful news: Khao Hom was gaining weight well, and the doctors were starting to plan her discharge.

The couple cried with relief. And almost immediately, a new worry arrived: our daughter is so small, how can we bring her home to a house that has just been underwater? This article explains the order for preparing the home and the nursery after a flood, for families in Lat Krabang, Min Buri, Prawet and nearby districts who are waiting to bring a premature baby home.

Why a Nursery Needs Extra Preparation After a Flood

Parents of premature babies are usually advised by the medical team to keep the home environment clean, to avoid cigarette smoke and dust, and to keep the baby away from people who are unwell, because the baby's body still has a lot of growing to do. A home that has just been flooded tends to contain several things that should not be near a new baby.

• Mold spores. Walls, ceilings, curtains, rugs and particle-board furniture that stay damp can grow mold within days. The spores float in the air that everyone in the house breathes.
• Germs from floodwater. Floodwater is commonly mixed with wastewater and sewage. It can carry germs linked to diarrhea, skin infections and leptospirosis. Residue left on floors and furniture legs needs to be dealt with completely.
• Dried mud dust. Silt turns into fine dust that settles on surfaces parents use every day, such as the changing table.
• Musty air and humidity. Stale, damp air is unpleasant, and it signals that moisture is still trapped somewhere in the room.
• Strong chemical smells. Pouring concentrated bleach or spraying perfume to cover the smell in a nursery can leave fumes and fragrances that are not suitable for a newborn.

Beyond health, there is the question of time and emotional energy. The weeks before discharge are some of the most exhausting for parents. They are learning how to care for their baby, travelling to hospital every day, and now they also have a damaged house to deal with. A clear plan, with a team to take on the heavy work, leaves parents with more energy for their baby.

International guidance such as the World Health Organization's material on floods consistently identifies damp housing and contaminated water as important concerns once floodwater recedes. What that means for an individual baby, though, is a question for the baby's own doctors.

Talk to the NICU Team First, Then Plan the House

Before you start restoring the home, let the nurses or paediatrician know that your house has flooded, and ask questions such as:

1. How many days before discharge should the nursery be ready, and are there any extra precautions you would like us to take?
2. Baby items that got wet, such as bottles, breast-pump parts, toys and cloth nappies: should we throw them away, or how should we clean them?
3. If the house is not ready on the day our baby can come home, where should we stay in the meantime?
4. What signs in our baby mean we should come back to hospital straight away?

The team's answers give the family and World Health Disinfection (WHD) a timeline to plan around. All baby items should be handled exactly as the hospital advises. WHD does not disinfect bottles or feeding equipment in place of the boiling or steaming method the nurses teach.

It helps to share the key dates with us when you book: the expected discharge date, any days you must be at the hospital, and when relatives can help. We schedule the work backwards from discharge so there is plenty of time for ventilation and a re-check.

Some families worry that asking the hospital about the house will delay discharge. In practice, NICU teams are used to helping parents plan for real-life complications, from long journeys home to crowded living situations. Being open about the flood lets them give advice that fits your actual circumstances, and it means that if the room is not ready in time, there is already a sensible backup plan agreed with the people who know your baby best.

Why the Usual Fixes Are Not Enough for a Nursery

• Repainting over the stains. If the wall is still damp, mold comes back under the paint, and fresh paint fumes are not ideal in a baby's room.
• Bleach, then closing the door. Fumes stay trapped in a closed room, and bleach does nothing about spores floating in the air.
• Air fresheners or diffusers. They mask the smell for a while without removing its cause, and strong fragrance is not suitable for a newborn.
• Fans to dry everything. Fans reduce humidity but also spread spores and mud dust.
• Keeping moldy curtains and rugs. Fabric that sat in floodwater and grew mold deep in the fibres is very hard to clean completely.

A nursery needs the right sequence: discard damaged items, dry the room, disinfect surfaces and air, remove odors, ventilate thoroughly, and only then set the room up again before your baby comes home.

The Solution: A Structured Disinfection and Ozone Treatment for the Nursery

WHD's disinfection service applies CHEMGENE HLD4H with an ultra-low-volume (ULV) fogger that turns the disinfectant into a very fine mist, reaching room corners, under the cot, behind wardrobes and along skirting boards. The ozone treatment service then treats the sealed room, helping to destroy airborne mold spores and break down musty odor molecules. Once the room is fully ventilated, ozone returns to ordinary oxygen and leaves no perfume behind.

How the work is done

1. Site survey. The team checks the water line, mold spots and wall moisture, and asks for the expected discharge date so the schedule allows enough ventilation time.
2. Advice on what to discard and what to keep. For example, a flooded play mat, curtains with deep mold and swollen particle-board furniture usually go. Baby items in good condition are removed from the room or sealed in airtight boxes.
3. Disinfection fogging with Chemgene HLD4H. Floors, walls above the tide line, under the cot, the bathroom and the hallway you will carry your baby through are all covered.
4. Ozone treatment. The room is sealed and treated for the assessed time. No people, pets or plants are in the house during treatment. Ozone-sensitive electronics are covered or removed, and the dose is controlled to suit the room.
5. Thorough ventilation. Doors and windows are opened until the ozone has broken down. We recommend allowing several days of airing before your baby comes home.
6. Re-check. Odor and mold spots are checked again. If walls are still damp, a follow-up round is recommended. Then parents set up the room and wash fresh bedding.

Lat Krabang Homes Stay Damp Longer Than You Might Think

Lat Krabang is a low-lying district on the eastern side of Bangkok, surrounded by canals and areas designed to hold water. Many housing estates were built on land that used to be rice fields or ponds. When heavy rain continues for days, water drains away slowly, and single-storey homes in these estates are often left standing in water for several days. Concrete walls and ceilings soak up a great deal of moisture. Even after the water has gone and the wall surface looks dry, the inside can remain damp and ready for mold to return.

Single-storey homes have another limitation: there is no upper floor to move the nursery to. The baby's room has to be on the floor that flooded. That makes thorough disinfection and odor removal, and patience before repainting, especially important for families waiting to bring a tiny baby home. If time is short, the family can ask the medical team whether staying with relatives for the first weeks would be sensible, and move home once the room is ready.

10 Reasons Lat Krabang Parents Choose WHD to Prepare the Nursery

1. We schedule backwards from discharge day, leaving enough time for ventilation.
2. A fine mist reaches every corner with ULV fogging.
3. A high-standard disinfectant: CHEMGENE HLD4H.
4. Fewer airborne mold spores through ozone treatment.
5. No heavy fragrance left behind, so the nursery is simply clean.
6. Clear safety rules: no one in the house during ozone treatment, and full ventilation before re-entry.
7. Honest advice on what to throw away, so you do not spend money on things that cannot be saved.
8. Respect for the paediatric team. Baby items and baby care follow hospital advice.
9. Care for the parents' bedroom too, with the dust-mite removal service for mattresses that stayed dry.
10. East Bangkok coverage: Lat Krabang, Min Buri, Prawet, Nong Chok and nearby areas.

A Family's Experience

"We were exhausted at the time, going to the hospital every day. The first thing the team asked was roughly when our daughter would be discharged, and they planned the work so the room could be aired out for several days. They told us honestly that the play mat and curtains should go, and that the bottles should be cleaned the way the nurses showed us. On the day we brought her home, the nursery no longer smelled musty."

A Short Checklist Before Bringing Your Baby Home

• The nursery has been fogged, ozone-treated and ventilated, and there is no musty smell.
• Walls are completely dry with no new mold spots. If they are still damp, postpone repainting.
• Sheets, blankets and baby clothes are freshly washed as the hospital recommends.
• Bottles and breast-pump parts are cleaned exactly as the nurses taught.
• General household surfaces are wiped with CHEMGENE HLD4H spray, which has no pungent smell.
• No smoking in or around the house, and visitors who are unwell postpone their visit.
• The hospital's phone number and follow-up appointment dates are posted somewhere easy to see.

It is also wise to think about the first few weeks rather than just the first day. A newly restored room can develop new damp spots if the weather stays wet, so keep an eye on corners and the bottom of walls. Placing the cot a little away from exterior walls and keeping the room aired during the day both help. If anything changes, a re-check is far easier than starting over.

Sorting Baby Things After the Flood: Discard, Wash, or Ask the Hospital

One of the most stressful jobs after a flood is deciding what to keep. Many baby items were gifts or carefully chosen purchases, and throwing them away feels painful. A simple three-pile system can make the decision less overwhelming.

• Discard pile. Anything soft and porous that sat in floodwater and cannot be washed hot: foam play mats, stuffed toys, cot mattresses, cushions, and cardboard boxes. Particle-board furniture that swelled also usually belongs here. These items absorb contaminated water deep inside and are very hard to make safe again.
• Wash pile. Clothes, blankets and cloth items that were in sealed containers or above the water line, and only got damp from humidity. These can usually be washed thoroughly and dried in the sun, then stored in clean, closed boxes until needed.
• Ask-the-hospital pile. Anything that goes in or near your baby's mouth or is used for feeding: bottles, teats, pacifiers, breast-pump parts and teething toys. The NICU nurses can tell you whether to replace them or how to clean them.

Take photos of discarded items before they go, both for insurance or assistance claims and simply as a record. Then let the team know which items remain in the room so they can be moved out or sealed before fogging and ozone treatment begin.

Looking After Yourselves, Too

Parents of premature babies often put themselves last. After weeks of hospital visits, broken sleep and worry, a flooded house can feel like one burden too many. It is worth remembering that the baby needs rested, healthy parents as much as a clean room.

When you clean up mud or handle flood-damaged items yourselves, wear boots, rubber gloves and a mask, and wash your hands and change clothes before visiting the NICU or holding your baby. Cover any cuts on your hands and feet. If you develop a fever, muscle pain or diarrhea in the days after cleaning, see a doctor and mention that you were exposed to floodwater. And accept help: relatives who can carry furniture, a team that can take on disinfection and odor removal, and neighbours who can bring a meal all free up time for the moment that matters most, bringing your baby home.

What About the Rest of the House?

A baby spends most of their time in the nursery and the parents' bedroom, but they will also be carried through the living room, into the bathroom for baths, and past the kitchen where bottles are prepared. Floodwater rarely respects room boundaries, so mold and odor in the living room or kitchen can easily drift into the nursery once the doors are open.

For most single-storey homes in Lat Krabang we recommend treating the nursery, the parents' bedroom, the bathroom and the main hallway as a minimum, and the whole ground floor if the water reached every room. The kitchen deserves particular attention because it is where bottles are washed and sterilised. Cabinets made of particle board that swelled in the flood often hide mold behind their doors and should be inspected, and replaced where necessary, before baby items are stored in them again.

Planning the whole house in one visit is usually more efficient than treating the nursery now and the rest later, because ozone and fogging work best when every connected space is treated together and ventilated together.

Frequently Asked Questions

Q: How many days before our baby comes home should the nursery be treated?
A: We recommend treating it early enough to allow several days of ventilation and a re-check. For precautions specific to your baby, please ask the paediatrician.

Q: I express milk at home. Do I need to leave during ozone treatment?
A: Yes. Nobody should be in the house during treatment or before ventilation is complete. Take the pump and stored milk with you, or keep stored milk in a closed refrigerator as the team advises.

Q: Can toys and bottles that were in the flood be ozone-treated and used again?
A: We do not recommend ozone treatment as a substitute for cleaning baby items. Ask the hospital whether to discard them or how to clean them.

Q: The particle-board cot legs are swollen. Should we keep it?
A: Swollen particle board usually has mold deep inside and may no longer be as strong. In most cases it is better to replace it.

Q: Do we need to treat the whole house?
A: We recommend at least the nursery, the parents' bedroom, the bathroom and the main hallway, because the baby will spend most time there.

Q: Can this article replace medical advice?
A: No. Anything about your baby should be discussed with the paediatrician and nurses caring for them.

Q: Which areas do you cover?
A: Lat Krabang, Min Buri, Prawet, Nong Chok, Saphan Sung and surrounding areas. Send us your expected discharge date on LINE @whd268 so the team can schedule in time.
