I am usually loath to self diagnose but something in another post struck a chord.
I do have a very strong letdown and DS always pulls off until it slows down. Sometimes he'll then take a good feed, other times he'll continue to pull off/fuss/headbutt/grizzle when on/scream when off etc. Sometimes is wind, other times seems not.
He has very wet nappies, poos during or after most feeds. Usually orangey yellow poo, green one every few days but with orangey ones either side (never a sucession of green poos). Possets after most feeds, big sick once or twice a day (sometimes doesn't but more often does).
He is very unsettled generally, if he is awake and not being fed he is screaming. Will lie on playmat or sit in chair for all of 30 seconds without screaming. I wear him in sling for most of the day (pacing/dancing to stop him screaming-even just being held isn't enough), can only transfer him to cot once deeply asleep. He will then usually sleep for a decent amount of time though.
He cluster feeds from 3/4am onwards (sometimes until lunchtime or beyond) and from 6pm until 10/11pm most evenings. Doesn't seem any dfferent at these times (ie no more or less sick/fussy) except he wants feeding constantly and won't settle in sling (proper deep sucking not comfort sucking, but coming on and off).
I'm not even sure this is a feeding question-other than the fussing at breast feeding seems to be the one thing that is actually going well (no pain/doubting myself etc). Have looked at Cranial Osteopathy but the only one in my area that does babies will only take block bookings of at least 5 sessions and at £35 each I can't really afford it.
He is now 6 weeks, has been like this pretty much since birth. Tried infacol/gripe water but no change (more sick if anything). To be honest it is starting to wear me down, especially as we pass 6 and approach 8 weeks and most other babies seem to be settling down/cooing/interacting etc (I know, I know, I shouldn't compare...).
I feel as though I should be enjoying at least some of the time with DS and so far I'm not really. My poor DD (20 months) is also suffering because I feel so shattered (physically/mentally/emotionally...)to play with her or even be able to with ds's constant screaming. she does enjoy the times I have him in the sling though as I can chase her round/dance with her etc but I feel guilty that it isn't time properly devoted to her
