Newborn wakes every hour at night

FTM and need some ideas! My baby is just over a week old. The first few days home from the hospital he slept great. He woke up every 3ish hours, we changed him he ate 2-3 ounces, burped and was back asleep. Well the last few nights starting around 9pm-7am he wakes up every hour. He wants to eat but he will seriously eat like 2 drinks and go back to sleep. And sometimes we lay him down and he wakes up not even 5 minutes later. I don’t know what to do but I need more sleep!
