Baby won't eat every 2-3 hours


My son is 2 days old and every nurse or doctor I saw said he has to eat every 2-3 hours. Problem is that he won't always do it. It ends up being closer to 4 or 5 hours and then he cluster feeds for a couple hours. He'd rather sleep and I can't get him to wake up to feed, he wants it on his teens only. No one at the hospital was any help with this at all. I'm worried he won't be eating enough. 😣
