Abigail is on follow on milk. I switched her to it because she had a run of colds / teething etc so she wasn't too consistent with her eating and I wanted to make sure she was getting enough. The other day at my mum's she had cow's milk for her afternoon bottle as my mum ran out of formula and she drank more than usual, so I think we are going to replace one feed at a time, just keeping her on the evening feed of formula until the weather gets warmer and there are fewer bugs around (weird logic I know, but I worry that if she is not eating well for any reason she might pick up more bugs if she doesn't get all her vitamins).
She has about 6oz in the morning, 3-4oz in the afternoon and 6 in the evening, plus three large portions of yoghurt every day and lots of cheese.
