At first I thought it was a fluke but now he is signing when he pees or poops. And well sometimes when it is just a stinky fart. But last night when my friend was over to help with Matt (while I am still an infectious pool of germs) he signed to her diaper and she checked and he had peed!!
I am hoping that this is a good sign he will be ready to be potty trained earlier rather than later.
