Nat 550ml was very forced and alot was done in his sleep, very hard to get him to feed while he is awake. Basically the amount we got into him was 345ml awake and even that was a struggle. If Em has 550ml that is great, but atleast you are not fighting with him to have it. The qty bothers me but more sooo does the fight and struggle we have to get it down his throat. I was even forced to syringe it down his throat last night. We do think it was the yoghurt, but time will tell I guess there is nothing else we have changed, I mean I have always fought with him but we normally always eventually get well over the 600ml mark and as per the dietician when we went to hospital she said for his age/weight/length he should be having well over 800-850ml.
