It's possible, according to this article. Who are these people?!!!!
My friend, Shannon, sent over the article and suggested I try it with Lainey. (Jokingly, of course.) These babies supposedly can signal at 3 or 4 months that they need to go potty. 12 weeks old?!
Jack is 16 months old and the only signal that he provides us is by waiting until he has a fresh, clean diaper on. I think we'll stick to the old fashioned method.
