Baby weight?

Izzy

My baby was born at 8lbs 7 ounces. First visit to pedi and she was 8.1. Today she is 8.4. Doctor told me to weigh her on Tuesday, she’ll be 2 weeks by then. How much weight do they normally expect newborns to put on within that timeframe? Is it sufficient if she’s back at 8.7 or would they want her higher?
