DS turns two this week, and in between baking party cakes I have been idly wondering whether I should be switching him over to semi skimmed milk (I vaguely remember reading official advice that you're supposed to make the change when they hit two). Just wondering whether others did this, or stuck with full fat? I'm particularly interested in whether cutting down the milk calories might encourage DS to be a bit more enthusiastic about his solids - he's not a terrible eater, but he never really tucks into anything with gusto. (NB the last time I had him weighed he was totally average weight for his age/height.)
