The groundwork for potty training has been laid for almost a year now. Grammy had provided a mini-potty way back when for Z to get used to the idea, and he would sit on it (fully clothed) while we used the toilet. So he has had the concept in his head for quite a while. This summer, Grammy bought him a full-sized potty so we could begin training in earnest, though we haven't had a ton of success. There were two days where we had tiny trickles first thing in the morning, but then he seemed to lose interest in it.
