FYI - this is from Rochelle's red health record book... it's just an approx.

5 days - 3 months: 150mls per kg of body weight per day
3 - 6 months: 120mls per kg of body weight per day
6 - 12 months: 100ml per kg of body weight per day.

I have been told otherwise by my Dr. He said you can overfeed a FF baby because it doesn't have the hormone in it like breastmilk to tell them they are full - that's the problem with formula. As a consequence it stretches their tummy and sets them up for obesity when their older.. Just like adults have over stretched stomaches and engorge themselves unnecessarily. I have seen an over feed FF baby and it's pretty sick! That baby was massive. I mean if she is crying because she is hungry after you have given her the recommended amount, well I would give her more. But if you are feeding her just because she is drinking it - I don't think that is necessary because as my Dr says, they don't know they are full when they are FF.. they'll just continue to suck because they love to suck!
