I believe that many mothers have had this experience: when the child is breastfed to 5 months later, one day, you are holding your breast-feeding baby in your arms, very comfortable and enjoying the pleasure of breastfeeding, and your heart is at peace, when suddenly a painful bite on the nipple comes, and the baby bites you hard. There are many reasons for this phenomenon, the most common being that your baby is teething and has a swollen teething bed and will have a need to bite something to reduce the pain. In addition to baby teething, if you use an artificial pacifier, nasal congestion discomfort, reduced milk intake or the need for more attention may cause your baby to bite your mother’s nipple. The point of solving the problem is to find out what the problem is first and then fix it. If it’s your baby’s first time biting you, stay calm and don’t scare her by screaming or cursing at her; don’t pull out the nipple in a hurry, but take a deep breath and let it out slowly. This is to prevent you from pulling your nipples in the heat of the moment. After being bitten, you can also suspend breastfeeding, give your baby a teeth fixer, and tell him in a serious tone, “Only this is allowed to bite, mommy’s nipple is not allowed to bite.” Don’t think that your baby is small and doesn’t understand anything, but in fact, she will react to her mother’s tone of voice. Perceive your baby’s sucking movements while feeding If you notice signs of teething, try to be alert while feeding. Usually when your baby sucks at the breast, he or she opens his or her mouth wide to take in the entire areola. The wrong sucking action is for the baby’s mouth to cover only the nipple, which can easily break the skin of the mother’s nipple due to poor posture. Therefore, when your baby is half full, you may want to pay attention to whether your baby’s sucking position changes. If your baby slightly loosens his mouth and slides towards the nipple, you should pay attention and change your baby’s position to avoid nipple bites.
