hi - my 6 week old is a real fussy feeder he has been ff since birth on aptimal with tommee tippee bottles - he was born at 8.4 and is now 10lb so not a great weight gain and is dropping on his centile - saw HV and no tongue tied that they could tell - I have used a 2 flow teat since birth as advised by MW as he had jaundice - It takes me an hour to feed him 3oz and he usually will only take 3-4oz more like 3oz every 4 hours. The HV today said he really should be taking 5oz and suggested Avent bottles instead and to maybe be go back to the cartons as its sweeter (recently changed to powder) - Its really worrying me - what might be wrong with him?? My dd gained at least 1lb every 8-10 days and drank at least 5-6 oz at this age - Any advice would be great - have seen GP and also have my post natal check next week, but am worried, tired and fustrated by it all - any advice would be great :)
