Hi, My daughter is 5 and turns 6 in September. She weighs 14 1/2 kilos. People are always commenting on how little she is, but she is bright, and active and doing well at school. She is a very fussy eater, and doesn't eat much. I have discussed this with my GP but they always say she'll eat if she's hungry and as long as she's healthy. She has a multi vitamin everyday. I have considered getting a referral from my doctor, as it's hard not to worry about these things.
