Any suggestions?

Today was my first day potty training my 33 month old son and I have some questions! First one is about nap time. Did any of you ditch the diapers right away or used diapers for a few days to a week to see if it’s dry then ditch them? Second, night time. My son has always used the Pampers Cruisers 360 since he was 9 months old. Now that we are potty training him, I am not sure what to do with night time. I have read some folks use pull-ups to associate it with special “diapers” for night time. The Pampers Cruisers 360 are pull-up style diapers but to use that at night, I feel like that can be confusing to him since he was in them at such a young age and we have so many of them right now that I don’t want to waste them either. The only idea I have is to get pull ups and let him know they are different from diapers because of the characters/design it comes in, but that means I am spending money on something that I already have.

What creative ideas did you come up with when it came to night time potty training? Any suggestions?
