Too much sleep?

Around 11:45 PM last night my little one fell asleep. She woke up at 6:15 AM for a diaper change & feeding. She fell back to sleep at 6:33 AM & around 9:45 AM started crying which I know meant she was hungry. I picked her up & fed her all while she was sleeping. It is now 12:15 PM & she is still sleeping. By no means am I complaining 😂😂 I’m just wondering is it normal for her to sleep this much. She usually sleeps 5 hrs at night then 3 hrs then 1.5 hrs throughout the day until 7-8 PM when she stays awake until 9:30 PM which is when she takes a 20 mins nap. She then wakes up until 11 PM - 12 AM. She’s not running a fever or sick in an way.
