My toddler never gets tired of taking plastic containers, pots and pans in and out of the kitchen cupboards and pulling books off shelves. Why is this happening and what can I do about it?

Your toddler is exploring! As her world expands, the more safe opportunities you give her to check it out, the better. So while it's just plastic containers to you, it's a cupboard full of fun for her -- and just one more stop on the route to growing up.
