my ds is 13 weeks and has hidden reflux. we have tried him on enfamil and he was very sick and constipated on it. we tried sma and he was constipated and seemed uncomfortable but was never actually sick - he just was very jerky. now on aptimil and he seemed to like the taste at first drinking 7 oz which is unheard of but now thats tapered off and he is jerky again. should i try farleys or cow and gate next? mentioned Nanny to the HV with a view to getting it prescribed (its 3 times the price of sma) but she wouldn't saying that doctors are not keen on it coz it doesn't have enough calories. someone , please advise me on what i should do next - i hate to see him so uncomfortable
