advice with 3 week old?

Samantha

So my daughter turned 3 weeks old this past Saturday she has been eating 3-4oz every few hours and I was told that was a lot for her age from a family member, not that it was a bad thing but just surprising and all day she's up to 4-5oz already! I googled it and that's a normal feeding for a 2 month old!? Just wanted some new momma advice about it and anything else if y'all wanna give any tips?
