Should I worry baby is sleeping too much during the day?

I wonder if my almost 8 week old is sleeping too much throughout the day. On average she’s still getting 4.5-5.5 hrs during the day. She’s a great sleeper at night so far!

Our schedule is pretty consistent with doing her bedtime routine and putting her down for the night between 10/10:30, and she’s out until at least 4/5, giving us regularly 5-6 hr stretches. We’ve had a few 7-8 hr stretches. She always falls back to sleep after that night feed and we don’t usually start the day until 8:30/9.

I’m noticing her sleepy cues (mostly just her eyebrows being red) and then getting her to nap. Or when we’re out and about she nods off on her own like in the car or when we’re out on long walks. I’m telling myself if she didn’t need the sleep, she wouldn’t be sleeping that good. But worry that I should wake her up or try harder to keep her awake for longer.
