My DS is 11 weeks old and has always had problems with his digestion, he cries and wriggles a lot around 2-3 hours after a feed (bottle fed) until he farts a lot which eases the pain. This seems to be getting worse and he's really screaming at times now. Often I think the nappy will be dirty especially if there is a smell but it's not but he is pooing about twice a day. We give him infacol before every feed and he is o a slow flow teat. Can anyone help? Is there anything we can do? Does it end as they get older?
