DD is 2.5 (actually31 months), goes through phases where she really doesn't eat much (usually with illness) but loses weight along with it. I find it quite worrying, the HV say she's fallen off her curve (dropped 1-2 lines since she was 12 mos) but more or less steady on the lower line. However, she's agains lost 700g in two months.
What do I do? I find it quite worrying, can't force her to eat but we're just coming off of another week with illness and food refusal. Between she often eats reasonably well but even so she seems to be losing weight.
