BF issues whilst pregnant

I am breastfeeding my 13 month old and are 7 weeks pregnant with #3. I am reluctant to wean. I breastfed my daughter until she was nearly 2.

The problem I'm having at the moment is he feeds great to begin with then he starts pulling off then wants it again. He does this over and over then bites me. My nipples are pretty sensitive at the moment anyway but this is really putting me off feeding. It hurts!

When he bites I sternly tell him "No that hurts mumma" and put him on the floor. He usually cries at this and at times I have too.

Any suggestions would be fantastic. I'm assuming my milk must be tasting different due to pregnancy hormones.

I'm really hoping my milk won't dry up! I wonder if my supply has reduced? He is still nursing 5 times a day, nothing has changed there.

Yes, I have been pretty tired. Both with the pregnancy, working and Sebastian not sleeping well at night. I haven't been aware of it affecting my letdown but will pay more attention now. Thank you.

I'm having the same issues. Well, Jude doesn't pull on and off but my nipples are sensitive and sore due to pregnancy. He can't seem to keep his teeth out of the way (no matter how many times I re-latch him - and he seems to have normal latch going on anyway) and he sometimes bites

Supply and let down seem to be fine, it's just that it's getting to the point where I dread breastfeeding. Doesn't seem to be much I can do about it. It sucks because I've never had any issues before now - BF has been a breeze so far, even when Jude was newborn. Really annoys me.
