My 6 year old worries me. She is so active I would almost class her as hyperactive. She bounces or runs everywhere. Games with her 2 year old sister and 4 year old brother ALWAYS involve chasing,instigated by her. At the dinner table she is always shifting on her chair. At school she seems ok but i know at lunch time she chases all her friends around. Her reading is quite behind no matter how much we do with her, and follow what the teacher says. however she can sit and play a computer or wii game for ages,and also colour in and do craft for ages,has a real eye for detail. Should I worry?
