3. Embrace the power of less.Don't be afraid to ruthlessly winnow the number of toys and materials in your child's room. If a younger child is having trouble letting go of old toys, try decluttering the room on your own. You will be amazed at how much more engaged your child becomes when there is less to focus on. First to go should be any toys that are broken or have missing pieces, and those that are no longer age appropriate. If that still leaves you with a heap of toys that are obnoxiously loud or bright, or drive you nuts, either give them away or save them in a special rainy-day box.A word of warning if you do remove toys in your child's absence: You may want to hold off on actually giving the items away in case you've mistakenly tried to get rid of a real favorite. The point is not to cause meltdowns but to simplify and help your child focus on beloved toys and games.
