My four year old never plays alone. He always wants to play with me. If he's not at school or im not at work he is attached to me like glue. He has no problems going to school. He loves it. He doesn't suffer with separation anxiety but if im around he just wants me to play with him all day. If i go to the toilet or go in bath he wants to sit and talk to me. And vice versa. He wakes up at 7 wanting to play a game with me immediately. How can I encourage him to sometimes play independently and enjoy it?
