My 16 week old son has been having COLIEF added to his expressed breastmilk since 6 weeks old due to wind. He has now started to wake up 4 times in the night, when he used to go through till 5 or 6 and he's farting and writhing in pain. I've tried adding more, adding less and not adding any, all without success. He is a little constipated and I think he's teething. I'm using TEETHA powder to chill him out but he's all over the place. I've tried massage but he screams! He does get plenty of wind up after his feeds but obviously not enough. Is increased wind and constipation due to teething? Can I do anything to help him? Does anyone have any suggestions?
