Newborn sleeping too much ?

I’m kind of concerned my baby sleeps too much. He’s only awake about an hour during the day and when he cries from wetting his diaper or being hungry and then he will cry for 4 hours on and off at night. I don’t remember my first son sleeping that much as a newborn. He had a lot of periods of time where he’d be awake. Ugh, I don’t remember. Maybe I’m just paranoid. I hate how bad my anxiety gets after birth. 😭
