Hey
This sounds so familiar - we had screaming constantly for the first 12/13 weeks. DS was referred to consultant at 4 weeks and it was a case of trying different combinations of meds and milk until we found the one that worked for us. He had silent reflux.
I was tearing my hair out at times and I had the support of my doctors so I can't imagine what it's like without their support.
DS slept upright on us for the first 8 weeks - would scream the second he was lay down. After 8/9w we worked out that he would sleep on his tummy (which I had a loooonnnng fight with myself about)
I tried Cranial Osteopathy as I felt i'd pretty much tried everything else but to be honest I didn't hold much hope and it didn't do much to help - so much so that the guy refused to let me pay and told me he couldn't do anything to help (and he was a highly recommended CO, not some backstreet guy) That said, though - there are plenty of people who will disagree and say it worked wonders for them - which was one of the reasons I tried in the first place.
WRT meds, we tried...
LF milk
Gaviscon
LF milk and Ranitidine
CMPF milk and Ranitidine
CMPF milk and Omeprazole
It was the last combination which seemed to make the difference to us but even that wasn't perfect. It didn't help that DS seemed to be a generally frustrated baby. He was on hyper alert from day 1!
He's now 9m and is much much better - in fact, we have been weaning the Omeprazole over the last few weeks and he had his first night without it last night - so far so good. As well as that, I have slowly been introducing bits of dairy too - the odd yoghurt, or proper milk on his breakfast etc. Anyway - it's a bit long but I just wanted to say there is light at the end of the tunnel - although the tunnel seems never-ending in those early weeks.
Looking back - I'll admit I so did not enjoy those days of 16/17 hour screaming. DS was our little IVF miracle and I hated that I wasn't enjoying what i'd wanted for soooo long. Now, he's amazing - a happy giggling baby. His frustration has diminished as he crawled early and is nearly walking now.
I guess i'm trying to say that it sounds like reflux which can be helped - but I don't think there's a miracle cure and whatever combo works for you will also need time to help too
Phew, that was long.
