How often does your one week old sleep?

I feel like my one week old sleeps non stop. I feel as though I only see his eyes open maybe one hour of the day. Most of the time I have to wake him to eat and he’ll nurse 5 minutes before falling back asleep. There are a few times in the day where he roots and wants to eat but it’s mostly me trying to feed him. Is this normal ? They said he didn’t have jaundice so I’m not sure why he’s this tired. Worried.
