Have you experienced this? And how do you handle it?

My son used to be SO good about it. We’d be driving and he would tell me he had to go.

He still tells me before bed and upon waking up in the morning. But throughout the day he’s more reluctant to tell me and throws a fit (even if I say ok I’m just changing you no potty right now)

Nothing happened that should make him want to stop. We still do stickers, kisses, and he loves fist pumps for going.

Is this a normal phase in potty training ? I’d really like him out of diapers before baby 2 Comes.

Any advice to get him back on track would be much appreciated!
