I'm completely confused about why, in the past 4 days or so, ds's latch has started to be really painful to the extent that I can see a blister forming on my nipple.
He has teeth but they aren't new, I can't see any difference in his position, though obviously there must be something! He massively favours my left breast and this is the one that is affected.
He has bitten me in the past but that was very different.
Any ideas?
