FTM here, I need help!

My baby is 5 weeks and 2 days old. I’m not sure if it’s possible for newborns to sleep too much, but my son has slept most of the day.

He is still eating and having wet diapers. He has eaten more at each feeding than normal (usually eats 3 oz every 2-3 hours and now eating 4-5 oz every 3-4 hours).

He slept from about 9:45 PM (yesterday) to 4 AM, he ate and went back to bed. He then woke up around 6:30-7 AM and ate, he then took a nap from 11:35 AM - 1:00 PM ish (only bc he was woken up by my dad 🙄) then again from 1:30 - 4:45. He had a blow out (lol) and ate. He’s now back to sleep, it’s 7:50.

Does this seem normal??
