My 9 week old son is currently on 8 ounces of SMA Gold and guzzling the bottles like there is no tomorow. He sleeps well and is very content otherwise, however sometimes in the mornings especailly I need to get a second bottle ready as its not uncommon to go through 10-11 ounces. I bought him SMA White for hungrier babies a few weeks back as he was going through a growth spurt and was advised that may be a solution. Mother in law intervened and said not a good idea to change babies milk as it could make him poorly. My husband was a big hungry baby too and she started weaning him gradually at this age. She has talked about adding something called Fairec to his bottles to fill him up, I've searched for this on the internet and cant find anything on it. Has anyone ever heard of it and if so what are your experiences of it. I dont want to strat weaning him at such a young age as I feel he is far too young and his digestive system wont be able to cope, alo worried about him gaining weight excessively as he is already 13lbs 13oz! He's not fat just big and long (was 8lbs 13oz at birth). Should I move on to SMA White as its supposed to be good for 'hungrier babies', so suggestions and experiences of moving up the milk scale welcome....
