Nearly 2 yr old still has a 7oz bottle (I know it's terrible but he won't drink it from a cup). I want to wean him off it entirely but feel sort of guilted in by the ads. Does it provide vitamins etc? He only drinks water during the day from a cup. Not fussed on cow's milk or juice. Likes smoothies in a carton and loves yoghurt and cheese. I want to ditch the bottle so should I just slowly cut down the amount or keep trying with the cup? Two Qs really- how to ditch bottle and is 2+ formula any use?
