Hi. DS3 is breast fed. He still feeds quite a bit. He has got top and bottom teeth, the top since last week. The pain when he feeds....I can't describe it. Absolute agony. It isn't biting, it feels like a razor blade, or a sharp needle. And it just started a few days ago. It is both sides. I am so sore, and he won't take a bottle! Not mastitis as I had that before.Any ideas?!? Please.
