My 5-yr old granddaughter is very advanced for her age and has a large vocab. From the time she was little she has been very strong willed. She spends most of her time around adults due to lack of kids in her neighborhood and church setting. She is home-schooled and has no siblings. She particularly in the last year seems to have a lot of mood swings, emotional outbursts, and gets very upset if things do not work out the way she pervieves it should. She has become very attached to things and has a hard time of letting go and trying to get her to go somewhere without her mother usually ends up in a very traumatic experience for everyone. She lots of the time does not seem to be a happy child, like she has a heavy weight on her. She eats very healthy and gets a lot of exercise, and has no known health problems. She does take dance lessons and does well in that group, very precise about such things.
Is this normal behavior? It is taking a toll on her mother.
