This PJ suit is a one piece, so it's especially good for keeping baby's lower back covered and warm. Features convenient snap domes part the way down from the neck and around the legs to facilitate easy nappy changes. Loose fitting and roomy for a comfy nights sleep. Made from 100% organic cotton pointelle, soft and breathable with a beautiful nostalgic quality. To minimise shrinkage, this fabric has been pre-washed at our GOTS certified factory.
