Today is a Sunny day, so why not use it for a fun game. Prepare two pocket mirror is one for baby and one for myself. Show the child how to let sunlight. Give him time to learn "not to lose" their "spot" and to manage them. Now start to play together. Maybe it will be a beautiful dance on the wall and maybe you will even play tag. When the baby get comfortable with the new solar friend, ask him to put "Bunny" on the Cabinet, on TV, on the couch. On all items, to arrest him? Experiment and play.
