My 8 week old DS is formula fed. He has aptamil profutura and I've tried switching him onto other milks before like cow and gate comfort for colic which didn't agree with him at all, gave him horrendous nappies, his wind was worse etc and generally wasnt himself so switched him back onto aptamil. He was born 9 days late and was 8lb 7oz at birth, as of Wednesday last week he was 12lb 2oz.
He's been taking 6oz feeds the last 10 days but is now draining every single bottle, I gave him 7oz yesterday just out of curiosity to see if he'd drink it and he took about 6.75oz... should I move him up to 7oz bottles? The feeding guide on the formula carton says 7oz feeds are for babies at 15lb / 3 months old so I don't want to overfeed him, but I think hes genuinely wanting more milk. MIL suggested hungry milk but switching his formula before was such a disaster that im reluctant, any advice?
TIA
