10 month old sleep

Hi mommas, I have a bit of a concern about my 10 month old daughter, last few weeks he has been sleeping strangely. She skips naps either in the morning or evening and then stays up for 5 hours at a time and is happy and playing away...

Today she went to daycare and woke up from her nap at 11.34am....it is now 6pm and she is playing away in a great mood and is definitely not looking to go to bed....

Is this a sleep regression ?

Or do some kids just sleep less?

She seems fine and happy but I'm worried she's not getting enough sleep for her age. Thanks 💗💗
