He's got a room full of toys he doesn't seem to play with. When a child has too many toys to choose from he may have trouble picking one. He may go from toy to toy instead of settling down to play with one for awhile.
Old toys become treasures when they come out of storage after a few weeks.
If your child gets several new toys on a birthday, holiday, or garage sale shopping spree put some away for later. Move toys to a new play area. A rolling cart can be used to bring a few items to another room. Combine different toys together. Take the animals out of the barn, add some small toy people and it becomes a school.
