I need potty training advice.

Janice

My son is 20 months old and is definitely showing a lot of signs he is ready to start potty training. He takes hours clothes off on his own. He takes his diapers off. He hides when going potty. He constantly pulls at his diaper.i have a potty for him already. I just ordered a few potty books. I ordered some underwear for him. Any advice would be great. He is non verbal.
