DD is almost 7 months and has just cut her first two teeth. When she just had boney little gums she would sometimes bite, and I would yell out and pull her off. But it didn't stop her. Now she has taken to not only biting me with her teeth, but also holding my nipple with them. I say "no" and stop feeding, but then she throws a tantrum because she's hungry. I've been really consistent about pulling her off the nipple if she bites, but she hasn't learned at all.
If this carries on, I'll have to stop BFing, which is a bit annoying as I'm too lazy to make up bottles. I'm down to 1 nipple already today and the other isn't looking too good.
