My 11 week old has been on hipp organic since 2 week old and has always struggled with constipation! I changed him to the hipp comfort as well as doc putting him on 5ml lactulose a day 6 days ago and not happy he is breaking wind so so much very foul smelling and the milk I'd very oily and his sick is clear so I have changed him back to the hipp stage 1 again have I done the right thing has anyone had similar experience with hipp comfort
