How much formula? confused ...help!?

Milk does need to be her main food intake and is very important up to month 12 and some doctors say Beyond this point ( even though full fat cows milk is ok ) But you are doing the right thing. Your putting that milk into her food and that way she is still getting it and all it's goodness. If she is happy to eat the solids containing the formula then great. It's better that she gets it then if she don't. Don't give up on the night bottle. Maybe give her a little less food at 8.30 pm but more at 11pm then I'm guessing she may take more and then settle. As I think she still may be a little full still at 11 pm if feed at 8.30 pm. Good luck hun.x
