Babies experience much discomfort because of improper clothing. Many fretful babies are uncomfortable because of being handled on their bare skin, particularly in hot weather when a parent's hands may be sweaty and salty and make the baby's skin uncomfortable. In hot weather, a light, soft, loose cotton garment that covers the entire trunk and upper arms and thighs will be most comfortable.
Chilling of the baby's extremities may cause congestion in the abdomen, where even a tablespoon of extra blood may distressfully crowd the organs. If the baby is also wearing clothing with tight bands, either around the abdomen or thighs, the stage is set for colic.
