Baby's Underwear Essential for wearing under clothes or even as sleepwear, baby underwear is composed of bodysuits and trousers in soft pure cotton fabric or with a touch of stretch, to ensure total comfort for the baby. ... Similarly, the inner labels are printed so as not to irritate the baby's sensitive skin. Available in packs or individually, our bodysuits have press-studs for quick and easy nappy changing. You can choose the type of bodysuit that best suits you and your baby. It can be short, long sleeved or sleeveless. It can be crossed, with a full front opening or it can have just a simple crotch closure. In addition, the footed trousers for newborns, also sold in packs or individually, have a slightly elasticated turn-down waistband for greater comfort and less pressure on the baby's tummy.
