My daughter is turning 11 in a couple of weeks. She is much taller than kids her own age and has always been at 100% of the growth chart. She has started showing strange behavior lately. Restlessnes with arms and legs, crazy facial expressions, she cant sit still, bouncing in to things, general clumsiness. is this normal behavior?
A lot of the behavior you just described is present in child Chat Doctor.  If she is doing well in school and hasn't had a bad evaluation or decrease in her marks you shouldn't be concerned about this disorder entering puberty can cause these symptoms because of the hormonal gush. I recommend doing the basic tests like a blood test of CBC, thyroid function test to role out organic causes of mood changes. I hope this helps
