Hiya, joy love is 5 weeks today and our gp suggested we change his milk to atapmil comfort for his constipation and colick, had been on colief before on the newborn milk. I changed him today and he is eating his bottles really quickly and in one go,meh inch he never normally did but he seems to be hungrier, he was going 3hrs between feeds and with the same amount is now only lasting 2 hrs. Has anyone experienced this?
