1 year old napping when it's school pick up

My 1 year old naps around 1.30-3:30 maybe a bit later only by 15 mins or sometimes maybe up before.

If he doesn't have a long enough nap he's super grouchy but woke up at 9 today so getting him to nap at 1 was hard its nearly 1.30 and still fighting sleep but I have pick up to do at 3 so he won't get long

What do u guys do?

Was told not to wake him so I havent

Whats your routine?
