My son wears a size 4-5 depending on the brand of diapers. He knows how to take his diaper off, I think he knows when he pees at times because he will point at his penis or grab it through the diaper, and he seems to have more control and not pee while changing or in the tub. I’m a ftm and I want to know when I should move to pull ups? I haven’t even though of potty training yet because I’ve heard boys take a while to learn. He is 1yr old and 2 months.
