New Baby & Nursery
Non-Toxic Nursery Checklist, Without the Fear
Quick answer
The interventions with the most evidence behind them are: low-VOC paint applied well before move-in, a certified mattress (CertiPUR-US or GOLS for latex), GOTS or OEKO-TEX bedding, hard-floor over old carpet where possible, and good ventilation. Most other nursery 'must-haves' are lower-leverage. None of this needs to be done at once, and none of it makes a measurable difference if the basics (safe sleep, ventilation, breastfeeding or formula choices) aren't right.
The high-leverage list
Paint and finishes. Paint the room with a low-VOC or zero-VOC paint at least 4-6 weeks before the baby arrives. Off-gassing is highest in the first weeks and tails off rapidly. Open windows during and after.
Mattress. Look for CertiPUR-US (foam) or GOLS-certified natural latex. Avoid memory foam without certification - many off-gas for months. A second-hand mattress isn't recommended (NHS safer sleep guidance).
Bedding. GOTS or OEKO-TEX Standard 100 cotton fitted sheets. A wearable sleeping bag rather than loose blankets, pillows or duvets in the first year.
Floor. Hard floor (sealed wood, lino, ceramic) is easier to clean and accumulates less dust than carpet. If you have old carpet, a HEPA vacuum once a week makes a meaningful difference to dust levels.
Ventilation. Open the window for 10-15 minutes daily even in winter. Indoor air quality is consistently flagged as more impactful than most material choices.
The medium-leverage list
- Solid wood furniture rather than MDF, or at minimum, MDF that's been off-gassing for several months and is sealed on all sides.
- Cellular cotton blankets rather than synthetic fleece.
- Wooden or natural rubber toys for the under-1 mouthing stage.
- A doormat at the entrance to the home - traps a meaningful share of outdoor pesticide and lead-dust residues.
The low-leverage list (do these if they make you feel better, but they're not where the evidence is)
- 'Air-purifying' plants - the studies showing benefit used unrealistic ratios.
- Salt lamps - no measurable air quality effect.
- EMF-blocking products - the evidence base is contested at best.
- Buying every product labelled 'organic' or 'natural' - look for actual certifications.
What actually matters more than any of this
- Safe sleep (back, firm flat mattress, no loose bedding, room-share for 6+ months).
- Avoiding smoking around the baby.
- Adequate ventilation.
- Feeding and bonding routines.
The product choices on this checklist are the polish on top of those fundamentals.
Frequently asked questions
Do I need an air purifier?
+
Useful if you live on a busy road, have wood smoke nearby, or there's mould. For most homes, regular ventilation, a HEPA vacuum and avoiding indoor smoking covers more ground than a purifier.
Is it OK to paint the nursery while pregnant?
+
Most current guidance suggests modern water-based low-VOC paints are reasonable to apply with good ventilation, ideally not by the pregnant person. Older oil-based paints are a different conversation. NHS guidance is worth reading directly.
What about second-hand cot furniture?
+
Second-hand wooden furniture is generally fine if it meets current safety standards and you can check it's not been stripped with lead-based paint (pre-1970s). The exception is mattresses - NHS guidance is to buy new.
