She's 12. And tall. And until recently was a little chubby - but the weight has just fallen off her and I would say she has a perfect figure now (not skinny). Up till now she has always eaten normally but in the last few weeks I've noticed she has started refusing pudding, or saying no when we share out chocolate on a Saturday evening. Neither of those things are a problem I guess but and more significantly she has taken to only eating half of her plateful of food and trying to dodge breakfast. She has also taken to eating really really slowly.
Now IME those are the strategies you use when you need to lose weight. She doesn't. I don't think she should lose any more weight - as it is her jeans hang off her. I thought it was just something to do with puberty and losing puppy fat but now I'm wondering.
What can/should I do?
