You’ll still need diapers for bedtime. He’s very young but if he’s showing signs of readiness, try putting him in underwear during the day and take him to the bathroom every 30 minutes. You will also need to teach him a way to tell you he has to go, since I’m guessing he’s not saying potty yet right?

We did potty learning naked. Then, upgraded to quilted unders after a couple weeks. Then, into big boy undies. We kept a potty chair out where he could see it at all times, even traveled with one. We are still working on poop. We probably have one poopcident a week. Still in a diaper for naps and bedtime.
