How do you get your child to like cow's milk? It must taste different to formula. We've been using 'ready to drink' carton formula which I think must taste like sweet UHT (I haven't tried it though), and it's always at room temperature, whereas I don't think cows milk can be served at room temperature as once opened it has to be stored in the fridge. Unless you warm it? I wouldn't want to give LO UHT cow's milk, I don't think that can be as good as regular cow's milk.
My LO is a year old and currently drinking about 3 or 4 cartons of ready to drink formula a day, although he's eating fairly well too. Although I know some people would think I was mad, I'd carry on with the formula to be honest if it weren't for the cost :(
