With babies... care providers may "usually" have a different nap schedule for babies... versus for the older kids.
So if they do or don't... then it is up to you... to talk to them about it, or choose another provider.
They do this one-time fits all 'nap' times...because, they have MANY kids to care for... and cannot practically, put a baby to nap, by their cues... as needed etc.
For me, my son at that age napped 3 times a day.
A baby... will get tired, about 2 hours or 3 hours max... after awake time.
Otherwise, they DO get way over-tired and then, being over-tired makes it harder, for a baby to sleep and may even make them "hyper" because they are over-tired.
My son, wakes at about 6:00am. When he was a baby, that age as your son... he would nap at about 9:00am at the latest. I went by his cues and simply knew when he was tired... which, sometimes even at 8:00am, he'd be ready for a nap. Then he would nap about 2 hours. Then woke up. Then, 2-3 hours later, he'd nap again and be tired and ready for one. And so forth.
I knew my son's tired cues... and then that beget me 'knowing' his nap "schedule." So yes, his naps were on a 'schedule' because that is when he'd be tired and need a nap... and would nap. Conclusively.
And yes, over-tired babies and kids... get MEGA fussy and then cannot fall asleep well. By then.
Usually, by the time you see a baby actually yawning and rubbing their eyes... they are ALREADY tired.... and could have gone to nap, prior to those signals.
all the best,
