Weaning confuses me so much sometimes 
9mo DD is (finally) a really good eater but we haven't actually introduced breakfast yet. She has a big lunch at 11.30-12, something like pasta with veg or chicken casserole followed by fruit, and a good dinner at 5.30, a sandwich or crumpet with cheese, a yohurt, more fruit, something like that. She drinks plenty of water.
The thing is we struggle to get 20z of formula in to her. She is offered three 8oz bottles throughout the day. The 'breakfast' and afternoon bottles she really dithers over and it takes several goes to get most of the bottle down, with the bedtime bottle being the only one she takes in one go.
I'm worried that if we introduce a solid breakfast as well she will drop her formula intake even more - so having had 3 or 4oz when she wakes up, after a solid breakfast she won't touch that bottle again.
Is this an issue at 9mo? Will it be ok if she only have 16oz-ish of formula, as she generally always has at least one yoghurt a day and frequently has either cheese or Philadelphia at some point too. Or is the milk more important than a solid breakfast?
