We can’t blame moms for being apprehensive about their baby biting while nursing. No one wants to feel like a chewing toy, after all, and especially on such a delicate and sensitive part of the body. Knowing the reasons why your baby bites while nursing can help you avoid it and keep your nipples safe from baby teeth.
Your baby is teething. When your baby reaches an age of 4 to 7 months, they’ll start showing signs of teething. As the first set of teeth comes in, your baby may be uncomfortable and cranky, and this is normal as the teeth grow and try to break through the gums. Just before the tooth comes through the gums, it may cause swelling and soreness. If you notice more baby biting while nursing during this time, it's likely due to your baby trying to relieve the pressure he or she feels on the gums.
Your baby is bored. Sometimes, baby bites while nursing may be simply because your child is bored. They’re distracted by the world around them. You’ll notice that this usually happens when they’re near the end of a nursing session and aren’t as hungry anymore.
Your baby wants more milk. It’s also possible that your baby is biting on your nipples because they want more milk. When your milk supply runs dry, the baby may bite and pull back, trying to get more milk from your breast.
Your baby wants your attention. Some babies might bite on their mom’s nipples when they seek more attention. If they feel like you’re not giving them your full attention, they may start biting.
