Updated 2026-11-12

Baby pajamas come in three main shapes, a handful of fabrics and several ways of doing up. The right mix depends mostly on your child's age and how warm your house is at night.

Footies, sleep and plays or two-piece sets

Fabric

  • Cotton is breathable, easy to wash and the everyday choice. Snug-fit cotton is the usual pick for 9 months and up.
  • Polyester and fleece are warm and often flame resistant, good for cold rooms.
  • Rayon made from bamboo is smooth and stretchy and suits warm sleepers, but needs a cool wash.

Fastenings

  • Two-way zips open from the bottom, so you can change a diaper without undressing the top half.
  • Snaps are quieter but slower at 3 a.m.
  • Pull-on two-piece sets suit toddlers who are learning to dress themselves.

How many to buy

Most families get by with five to seven pajamas per size for a baby, because of leaks and spit-up, and three to five for a toddler. Multi-packs are usually the cheapest way to reach that number.
