Potty training

Did anyone else’s 2 year olds decide they want to be potty trained? My son one day started wanting to go to the potty, and wouldn’t get off until he wiped AND flushed even if he didn’t go. It was so out of no where which is good because I didn’t want him to feel rushed just because I wanted him potty trained. How do I reward? What are some good treats? I was thinking lollipops or cookies. Maybe some stickers? First time mom, so I’m all new to this! He’s been doing really good with using the potty, and saying he needs to go, so follow his lead?
