how are you adapting naps?

For the last few months I’ve had to enforced naps for my puppy and it’s been very consistent around the same times each day. I noticed she’s able to settle down in her playpen.. not outside of it yet haha. But it’s a start. It seems to me we can slowly adapt to a more non structured nap schedule.

I’m just worried because I usually use her nap times to leave the house so I’m scared if I don’t follow a schedule, she could still be awake when I need to leave the house and idk I guess it’s more crate training but i’m a bit lost on how I should approach this since I’m a very type A person and she’s been extra clingy and starting to resist her crate. Which is funny because when we do crate games it’s like she knows it’s just a training session so she’ll jump right in and won’t protest.
