Okay so I'm not sure when to introduce potty training but I am in the first trimester of my pregnancy and my son is 15 months. He's very good at taking his diaper off even with his onesie on. I want to get him potty trained kind of early to eliminate buying SO many diapers since their is going to be a new born in the fall. what would be a good time? He learns good and pick up on things quick and even figured out the baby proofing lock I put on my toilet he doesn't always get it but he knows how which keeps me VERY BUSY. any suggestions on when and what type of potty to get my son?
