DS has horrible colic. breastfeeding fine and doesn't seem to be taking in any air.... but screams and pulls his knees up for ages sometimes. random times day/night but sometimes we can't lie him down at all between feeds so it means one of us is constantly upright. we tried sleeping upright with him in baby carrier but he doesn't always sleep- just wakes up screaming. we are doing "shifts" between feeds at night but it means that we barely see each other. DP has to have more sleep as she is working full time, sometimes i can nap during the day if he decides to sleep but other times not. he's on infacol.... any other suggestions?
