How much did ur baby Weigh at 2 months

My Chicken Nugget was born at 6lbs 10oz and at her 1st check up a week later she weighed 7lbs 6oz and was told she needed to put on alil weight. She wasn't under weight but wasn't within her percentile. Now at her 2 month (shots) appointment she is at 11lbs 3 oz. I was breastfeeding until I was told she needed formula as while cause the breast milk wasn't enough in which I agreed so I started doing both breast and formula now I'm just on formula! But with all that said just wanted to know you guys babies weight at 2 months.
