I agree with what Kmn said about emptying one boob before going on to the next one.

From what you describe, it sounds like it could be an intolerance issue, or, if he hasn't dained the boob, a case of not getting enough of the fatty breastmilk (the first bit of BM that comes out is like a drink, then it gets creamier - it could take a young bub several minutes to get this "drink" before getting the "meal").

As for someone to talk to - a GP could hame a recommendation, as it may be an issue to do with mum rather than bub (you're saying the bottle worked, so it could be something the mother is eating, something on her skin, etc - a GP could have a look and them refer them on to the necessary people).

On a final note - what an absolute shame that the ABA lady was so rude. I know that ABA counsellors go through rigorous training to ensure that they are caring and professional at all times, but as with every organisation, there a few bad ones that ruin it for all. If you remember the name of this counsellor, I recommend that you repot her to the ABA head office, as she either needs more training or sholdn't be taking calls at all.
