hun I don't think its a good idea to limit her at this age. I think there is a high chance that could just lead to her wanting food more (because she can't have it) IYKWIM? And then you've created a battle ground over food. I've also been told they naturally graze at this age and probably, if I did that much running and jumping and climbing and dancing and all the rest of the activity I would drop my weight and be able to eat like a horse too

Is she overweight? I think if she's in normal limits then it's all cool.

DS is a bit like Nelle's, he runs hot and cold with meals. Sometimes he eats heaps and other times he seems to skip meals, sometimes two in a row He also grazes constantly most afternoons from about 3pm through to dinner-time. Often CC report that he "ate heaps" or "had seconds today" and those are the days he doesn't want much dinner.

Is she having a growth spurt?
