Gained too much weight?

My baby will be 7 weeks on Wednesday. He was born at 6.10lbs … his first 4-5 weeks he was mostly bottled fed (breast milk and some formula) sept 1 it’s full time nursing. A random 2oz bottle before bed and maybe early morning with more breastfeeding if He’s still hungry. He is currently 11lbs. At his 2 week check up he had already gained 2lbs.. he was eating 3oz already. So is my baby gaining a lot of weight for being 1 month .. he will be 2 months on the 27th.. and I have his dr appt then. He is forever nursing 🤱🏻 and sometimes uses me for comfort. Here’s my little big baby
