Hi everyone
I have an almost-8-week old who I was breastfeeding great till last week. Then he suddenly won't latch on properly. As in, no matter how much I try, he just won't open his mouth wide enough! Its been so perfect so far, I wasn't ready for this so late in the game

I normally touch the nipple to his nose, he puts his head back and opens his mouth wide, and in it goes. Even his health visitor and the mid-wife commented on how text-book his latch is.
Now he just won't open his mouth and even if the proper amount of nipple goes in, he will slide it out within a few sucks till he just has the tip in his mouth and THEN he will start sucking. Its excruciatingly painful, as you all must have experienced, and its utterly useless because he doesn't get much milk that way. The more I try re-latching, the more hysterical he gets and refuses to open his mouth bigger than a pound coin.
I'm bloody on both sides and have a huge blister on the right from the friction of his gums where he's biting. For two days I've expressed from the right to help it get some rest. I alternated him between feeds as:
left breast - bottle - left breast - right breast
So the right gets bitten (OUCH) every 6-7 hours or so. But its a lot better now.
He LOVED the bottle and those have been the few times he's actually taken all 3.5ozs that I can express, in, and then slept well. Before that, his sleep has been terrible all week because he'll wake up every hour hungry again.
Shall I shift him to the bottle for the achy right breast ... will it confuse him so he stops feeding directly at all? Will nipple shields help instead? I LOVE the intimacy of feeding and the bond with him and I really don't want the bottle if there's another option

Has anyone here tried nipple shields and then stopped using them when LO stopped biting?
