Thanks ladies for your suggestions... He woke for a feed (while almost asleep) and was fine on boob and emptied one , but I know that maybe because he was almost asleep.
Last night it wasn't like he didn't want to to on boob, he would start but after a few seconds and having a little milk he would get frustrated and cry or scream - I thought it could be wind but in previous occasions wind would sort itself out in an hour max, not last night. I thought it could be reflux, but when he took the bottle he invalidated both assumptions.
Could it be the taste of my milk that frustrated him that much?
At this hour, after feeding him, I had to express the other side as was getting painful...
And two conclusions, firstly Fate (I think it was you) you were right in that expressing is not indicative, I got 150ml in 12 minutes from one side when full , but 150 ml is still not much as in the past couple of weeks he hasn't been feeding for very long unless asleep ..
Secondly for Red, the content of fat in an empty breast is definitely different with a full one and my boobs are hardly full these days... (Although it appears you may not need this info any more :) )
Red the move is certainly interesting... Nothing like that here, although he managed a few inches on his tummy , it was after attempting hard and getting frustrated towards the end
Acron ds was born with some difficulties and they had to do a blood test for him a couple of months ago, as they were doing the test anyhow, they decided to test for milk protein too.
It is certainly interesting what you say that he got worse again, my gp told me it was unlikely his reflux got worse after getting better for a while - I think he just didn't come across one and didn't know- so he advised me against adding Gaviscon dose or starting Ranitidine, but the way ds has been getting uncomfortable again when feeding, and not wanting to feed as often or as long as previously, makes me feel reflux is getting worse...
