My 7 month old has been having a really tough time with naps at daycare lately. He's been having 1 nap a day, for roughly 20 minutes. I feel like this can't possibly be enough. Some days he passes out on the 15 minute ride home in the car because he's exhausted. The couple times I've brought it up with his teachers, they just tell me he's happy all day and when they put him in the crib he just plays and doesn't go to sleep.

I feel like daycare could/should be doing more to get him to sleep, but I'm not sure what to suggest. We've been sleep training him at night and lately he goes to sleep after rolling around the crib for <5 minutes.

Any suggestions on how I can bring this up with them? I'm also not sure if I should talk to the director since the teachers in the room haven't been very helpful.
