Laranna - could be a fast flow - maybe he just can't keep up with it and he's choking a bit? Can you hear him making little choking/gagging sounds? If its colic the pharmacist at Padbury does his own mix and its absolutely brilliant. Elena has had huge colic/wind problems this week and having tried the Brauers, Infacol and Infant's Friend without any success I went today to Padbury to buy some. I've given Elena two doses today and she has so far had a 3.5 hour sleep and is down again at the moment - 75 minutes so far and still out like a light and we've had no screaming today at all. It is really brilliant stuff and well worth the drive to Padbury even if its not convenient to try it if you think that's what his problem could be. I have friends that have all used it too and we all swear by it.
