Lately, Aidan has been very interested in the toilet, and is starting to understand the whole going-to-the-bathroom process. If we ask him if he needs to go potty, he will pat the front of his diaper and point to the bathroom. We sat him on the toilet a few times, and nothing came out, but he thinks it's fun so who are we to discourage him??
We decided to go buy him his own little potty, and while he enjoys playing with it, he does not want to sit on it.
To him, it's just another toy. Nothing beats the real potty for him, so I guess we'll have to get a baby seat attachment for him to try!
