9 month old's top teeth digging in - owch! Any advice?

[Parsnippercy]

Stil BF morning and evening but finding it pretty uncomfortable as his top teeth are digging into my nipple (bottom teeth fine as tongue in the way). Is this a bad latch? He tends to sort of pull back on the nipple as he's feeding which doesn't help. Not sure what can do but don't want to stop feeding because of this. any advice?

Would pulling his head nearer to the breast and gently pressing on the boob near his nose to allow him to breathe freely help? This may prevent him pulling back from the nipple.
My DD had plenty of teeth and it was never an issue re teeth, except when she bit, and a few screams from me shocked her so much she stopped!

Will try that, thanks. Have had biting probs but did same as you and didn't last more than a day or two!
