Wondered what others' experience of this is? I know they peak at 6 weeks supposedly . My LO is suddenly crying loads more since turning 5 weeks. It sometimes starts with an obvious cause - wind & pooing are more bothersome to him since he had a tummy bug 11 days ago (seen GP & he's ok), but then it can go on for ages, though he will be consoled for short periods by being held while walking up & down, going in sling, vibrating chair, playmat etc. but then crying quickly starts up again. Finding it quite tough going & feel sorry for little guy!
