DS is 14 months and is bf. When he was 12 months we started giving him a bottle of formula before bedtime in hopes that he'd disassociate bf from sleep. All went fine. He'd drink all 8oz.
We mixed whole milk with the formula to start with, after about two weeks of him getting used to the bottle. If it's just 2oz of whole milk mixed with formula he'll drink maybe 4oz and be done. If we add anymore whole milk he'll just refuse the bottle and if he does drink some he's often a little sick and seems uncomfortable, he's not a sicky baby usually. I wondered about a mild allergy, but he was always fine with the formula and eats cheese like there's no tomorrow!
Anyone else had this problem? The HV said it's really important he drinks whole milk. He's still breastfed during the day.
