Overfeeding?

My daughter is 8 days old and is always hungry! She can drink 120ml/4oz every 2 hours, I’m worried that I’m over feeding her

At her 5 day check up, she went from 7.8 lbs to 7.10 lbs, the midwife said it was a good thing she had put on but I don’t want to be doing something wrong with how much she is eating
