Spin off from another post!

What do you have in terms of a learning tower or a step stool for your LO? Do they ever use it for nefarious purposes?

We have a little cheap step stool that is just enough for our son to stand on so that he can pee in the potty, and beyond that, we have no other step stools or learning tower types of things. He loves to push a chair over to whatever he wants to reach (that he shouldn't be trying to reach!)

I'm trying to decide if we'd really use something like this or if it would just become another tool for him to get into trouble!
