Over a year ago I posted about using a hula hoop as a clear boundary for training a little one. It is one of those neat little tools that works for us when house-proofing a child. This was an idea I'd written about awhile ago, but on the day this photo was taken, we put it into practice while I made dinner. She was on the floor near me and she played with blocks and a doll.
I like the hula hoop because the parameters are clear. She has no problem understanding where she should be (inside the hoop). She was two at the time and she did quite well in the hula hoop for about 20 minutes.
