3 week old constantly hungry!

Leah

So my son is 3 weeks today. He has been eating every 2 to 3 hours the last week. Today its like he turned into the milk monster and eats almost 2 to 3 ounces every hour! Then when he falls asleep and so I put him down he wakes up 20 minutes later crying. I currently pump and also supplement formula. He has a hard time latching so he is bottle fed. Is anyone else going through this?
