I have completely confused my self by too much googling and now I don't have a clue what I'm doing 
Ds2 is 19 weeks olf and ebf. He has several of the symptoms associated with so-called foremilk-hindmilk imbalance, but I spoke to a bf consultant last night who basically said not to worry about that as he is growing and developing as he should. However, I am still worried as he never stays on the breast for very long, and I never know whether I should be swapping sides or not 
He feeds for about 3-5 minutes, in several goes (ie he comes off and I put him back on) then refuses to go back on. If I offer him the second breast he will sometimes take it sometimes not. I know he isn't emptying the first breast, though, because I can hand express and jets of milk come shooting out!! It's like he gives up when the inital letdown is over? Though I have no idea really...
So which side am I supposed to put him on for the next feed? If I try feeding from the same side again at the next feed (3-4 hours during the day) the other side gets painfully full by the next feed
.
I just am so so so confused!!
