Newborn over eating??

Isabel

my son is 1 week old today. he is formula fed & the past 3 days he’s been acting super hungry. he was eating 2 oz every 2 hours (wouldn’t make it to 3) and now he’s eating 3oz every 2 hours (barely making it to 2) I feel like that’s too much for a 1 week old and i’m scared i’m doing something wrong ☹️ is this normal???
