Clothing for preemie babies is very difficult to find, so we always try to carry some styles whenever we find a suitable supplier. Typically these items are sized by the baby's weight, rather than the nominal age ranges used for larger babies and small children. Petite Ami, Babyworks and Rumble Tumble usually size their preemie wear for up to seven pounds. Remember that premature babies have extremely delicate skin, so they need specialized fabrics. The clothing we carry is primarily aimed at smaller full term babies.
