We were talking today about how we think Simon is becoming more aware of his bodily functions. Micah said something like, “Before too long he’ll be ready to potty train.” Simon, who was sitting nearby, got all excited and started to sign something. We were confused. He was signing “train.” We’d been talking about using the toilet and . . . oh, wait, we got it. Train. Potty train. Hahaha. And immediately this image (or something like it) popped into our heads. I think we could make a killing putting it on toddler shirts.
