Potty training

Hey mamas! I just started potty training my 22 month-old because he showed signs of readiness and I think it’s going well for only being 3 days in? I just have no experience doing this and have never been around a kid who is getting potty trained so I just keeping thinking of random things for example

1) he tells me when he has to pee but I have to be pretty quick about getting him in the potty. So how in the world do I go somewhere?! I feel like putting a diaper on is confusing because he will pee in that but he knows to use the potty when he has his undies on or is naked

2) should I just do pull ups or diapers at nap/bed time?

3) he has his little potty in the living room (quick access), how do I eventually get him to use the regular one? 🤪

These are probably really doing questions but help a first time potty training momma out? 🤣 other tips/hacks you’ve learned feel free to share as well!
