:yeahthat: It's a good idea to give full fat dairy in general until they're two.
My DD is two, but I still give her full fat because she's a skinny little thing and her diet isn't so great. She doesn't drink heaps of milk but has a yoghurt each day and sometimes cheese if it is melted on toast.
Also, if you're just starting on the cows milk, while they are still younger it is good to heat it up a little as that breaks down the protein in there. (Not sure if this is relevant to FF kids, but when Natty refused the breast at 11 months we had to go onto cows milk and this was the advice given to me. Sometimes the cows milk protein can be difficult to digest, however formula's based on cows milk isn't it? So maybe that's not so relevant...)
