Newborn clothing can sometimes only be used for a short period, and some babies may already need a larger size soon after birth. Choosing 0–3 months or a later size can give parents more opportunity to use the gift, but you should also consider the baby's expected birth size and season.

A newborn wardrobe commonly includes comfortable sleepsuits, bodysuits and soft layers that are easy to change. Rather than buying a large number of pieces in the smallest size, parents may prefer a mixture of sizes that can be used as the baby grows.

A sleepsuit generally covers more of the baby's body and is commonly worn as a complete outfit or for sleep. A bodysuit typically covers the torso and can be worn alone in warmer conditions or underneath other clothing as a base layer.
