When my daughter was still little about 5 or 6 we always knew when she was really sick because we ask her if she wanted to play and she grab her little chair and sit down to play. That's when we knew she was sick for sure. She was always my little wild card she never sat still. Even in my stomach. The doctor said he never seen a baby move around so much while still in the womb.
Now if she says she is to tired to play her computer games and it isn't bed time or near it than she is sick.
