Bottle nipple confusion, or nipple confusion, is a common reaction: the baby is able to suck on the nipple but cannot suckle, the baby refuses to suck on the nipple, and the baby is able to try to suckle but suckles incorrectly. Nipple confusion is usually caused by the fact that the newborn baby did not breastfeed after birth and sucked on a bottle first, or the frequent use of a bottle causes the baby not to suck or refuses to suck on the breastmilk. It is mainly the baby’s movements and techniques that create confusion in the sucking process. The difference between sucking on the bottle and sucking on the nipple is that when sucking on the nipple, all you need to do is to gently close your mouth and suck, and the milk in the bottle will flow out due to the negative pressure of sucking. Sucking on the breast, on the other hand, requires the baby to use the tongue and jaw to cooperate in squeezing the areola position. When your baby has nipple confusion, seek professional help to correct it promptly.
