Hi - i tried my 12 month old on cow's milk a few weeks ago - mixed 2oz of it with 4oz of formula and she was really sick. She has it in her cereal and has cheese and yoghurts- although I have noticed if she has a whole yoghurt in the evening she is also sick in bed. I have kept her on number 2 formula and have just bought some number 3 but have read they are full of sugar? Is there an alternative I should be considering? Thanks
