Nursery Prep: 5 Tests Every New Parent Should Run Before Baby Arrives

The months before a baby arrives are the easiest time to do environmental testing on your home. The room is empty. There's no infant lying in a crib while you're collecting samples. And whatever you find is much easier to fix before a tiny person is breathing the air in that room 16 hours a day.

The five tests, in order of priority

1. Water — comprehensive lead, copper, and bacteria panel from the kitchen tap and the closest bathroom

2. Lead paint — XRF or chip sample on any pre-1978 walls, windows, or trim in the nursery

3. Air quality (VOCs and formaldehyde) — especially if you're painting, installing new flooring, or assembling new furniture

4. Radon — every home, every state, before baby's first night home

5. Mold — air sample if there's any history of leaks or basement dampness, even minor

Special note on new furniture

Cribs, dressers, and changing tables made from particleboard or MDF off-gas formaldehyde for weeks. Assemble them at least 4 weeks before baby arrives, run a HEPA-and-carbon air purifier in the room, and ventilate aggressively. Look for furniture certified to GREENGUARD Gold or CertiPUR-US standards if you're shopping new.

Special note on hand-me-downs

Hand-me-down cribs from before 2011 don't meet current safety standards. But beyond crib hardware, also pay attention to the source. A crib that lived in a basement might carry mold spores in its soft surfaces. A wall-mounted shelf from a pre-1978 home might be coated in lead paint. When in doubt, test.

What to do with results

If anything comes back high, you have time. Lead paint can be encapsulated. Radon can be mitigated. VOCs decrease with ventilation and time. Most water issues are solved with a $200 reverse osmosis filter. You won't fix everything before delivery, but you'll know what to focus on first.
