Also after baby bites, take a break and don't latch on straight away
It hurts so much! Those little teeth are so sharp! Another way besides pressing their face into your breast is to calmly say, "no biting" and use your finger to unlatch baby. https://kellymom.com/ages/older-infant/biting/
I say no, take him off the boob, and end the breastfeeding session. A lot of times he's simply not really hungry or his teeth hurt.
Mine will do this especially at the end of a feed when he isn’t hungry anymore and just wants to play around and smile up at me with his little gremlin face 😅. I usually just end the feed immediately and don’t feed him again right away. Gotta make sure he’s actually hungry and not just in a mischievous mood!
My son did this, and what worked was gently and quickly pressing his face into my breast and he would release for a breath. Sounds a but harsh, but it broke the habit pretty quickly. Also they can bite with a deep latch so work on that too. It's hard when they get so distracted.
