First of all big

My DS4 was similar to what you are saying of Shae, I too would also end up crying and wondering why he wouldn't feed from my left breast. I found that he only had a little mouth (he was 7lb 4 and the others were over 8lb) compared to my other boys as well as had slight tongue tie (not saying this is the case with Shae), that the Pead had not picked up on, on discharge. It took my DH to tell me to calm down and relax a little for him to slowly take that side. In the end we ended up feed two weeks shy of 18mths.

It's still early days for you both and you are both learning a new thing and it may just take a while for you both to get the hang of it.

Big to you both.
