Assembling a crib



For sleeping, the crib and mattress are the biggest investments you'll make, and aside from a fitted sheet, the only things you'll actually need for your baby, from newborn to toddler. Recent safety advice advocates no co-sleeping, and sleeping in the same room as your baby for at least the first six months. Cribs can be made of solid wood, metal, or pressed/laminated wood. They can be finished with paints, varnishes, lacquers or, if made of metal, powder-coated. Cribs are durable, and can be used by many children, so long as they are made to current safety standards and are free of harmful chemicals. 

Hidden Hazards

Formaldehyde is used in the adhesive that binds pressed board (like MDF), particle board, and plywood together. It can also be used as glue or adhesive with solid-wood furniture. Older cribs sold before 2008 may have been painted with lead-based paint. Metal cribs can be "powder-coated" with an material made with bisphenols. Often, cribs come with plastic bite guards (as babies grow and stand, they can chew the top rail) and some are made of polyvinyl chloride (PVC).

Other Considerations

Second-hand cribs may not meet current safety standards that were set to avoid trapping or seriously injuring babies. Cribs with the following features are no longer legal to sell new: drop-side fronts and widely-spaced slats (Current US maximum in US is 2 and 3/8" wide).


You can maximize an investment in a high-quality, solid-wood crib by choosing a model that can convert to a toddler/day bed. Depending on how fast your child grows, this can extend its life to 2-3 years. Make your choice last by opting for a solid-wood crib with zero or low-VOC finish, or consider unfinished solid wood. Ask about glues, even with solid wood. If you choose a crib made with plywood, laminate, or MDF, ask about VOCs and formaldehyde - and seek those that are certified to CARB (California Air Resources Board) Phase 2 limits.   Shopping on a tight budget? For better and worse, formaldehyde leaves products made with it early in the product's life. Recent second-hand cribs with fixed sides and narrow spacing of slats are worth considering.  If you do buy or are given a crib that smells strongly out of the packaging, consider setting it up as soon as possible in a well ventilated area. This could be a garage, or in the new nursery room, with the door closed and the window open enough to allow fresh air in.
