But it is proving very difficult. DS has vomited large amounts since he was pretty much born. HV recommended changing milk (didn’t work) and a GP wanted to rule out an allergy so prescribed him alimentum milk which made him worse. On Saturday morning, he resembled the exorcist. It was just coming out and out and he was screaming. I was at a loss and phoned 111 who advised me to take him to the walk in centre. They weighed him (he’s 6 weeks old) and he was 11lb exactly (he weighed 8lb 2oz at birth) They said he weighs more than he should and that 5oz is way too much and that’s the reason for his vomiting. They told me to feed him 3oz and if he wants more then to ignore him as apparently babies don’t know when they are full so they’ll just keep sucking and sucking. But only giving him 3oz is proving really difficult as he just screams and screams for more and then I feel awful. Of course the doctor probably knows better than the box of aptamil, but on the tub it says 4-8 weeks old should be having 5oz? I possibly may have read that wrong so I’m not sure. I’ve only been trying him with the 3oz since Saturday, should I just persevere? Will he eventually get use to it?
