i never new that Aiden had reflux until his 6 week check up when teh paed said he did. before that, i figured he was a happy chucker, but, after that, he started to get pain as well. I sometimes think it might of been due to a change in formula - i had put him on to the karicare gold plus, and 4 days later, he started screaming the house down.. (mind you, it was one feed a day, the rest was ebm)
