Why does my baby make a clicking sound while breastfeeding?
The clicking or chirping sounds some babies make while breastfeeding is the sound of air rushing in as the baby releases the suction on the nipple. The baby will do this after getting a large mouthful of milk. Clicking is almost always normal. It may happen only at the beginning of a feed or all the way through, and it’s more common when the mother has a large milk supply. The release of suction should not hurt the nipples, but it may be painful if the nipples are already sore.
