DS is 6 months. He was a terribly fussy newborn, showed signs of silent reflux, but eventually over supply/fast letdown issues were diagnosed. Various management techniques helped, along with Colief. This presumably helped with the lactose overload - I don't really know, only that it made him into a different baby.
However, he stopped sleeping, in hindsight, probabaly around the time I stopped giving colief (D'oh!). It was such a sleep-deprived blur I am not sure (instructions said they shouldn't need it much after 12 weeks).
All I know is I now have a 6 month old who wakes just about every 1 1/2 - 2 hours with flatulence (very smelly and noisy) and what appears to be stomach ache. I sometimes feed back to sleep, sometimes just pat/cuddle (co sleeping as only way I can survive this). He writhes around, grunting and clearly uncomfortable, though not fully awake and can do so for hours, or just frequently for a few minutes.
He is EBF. I have been dairy free for 3 weeks now and saw little effects except his (minor) excema cleared up (oh, and I am starving!). He is hungry for solids but when he has them he is up all night with stomach ache and flatulence (tried 100% baby ric with ebm and fruit/veg etc, all same results) and diahorrea the next day.
The last 4 nights I have given him Colief before bed. He slept 6 hours! Then last night back to being awake all night 
Just as I thought I'd cracked it. This can't be right can it? Do I need to cut our soya too? I am awating referral but so desperate for sleep right now would love to understand the cause of his wind problems. I feel my older DS is missing out as I am so tired. Can anyone give me any advice, I understand so little about allergies and suchlike.
DH has hayfever and FIL has excema btw.
