2 month check up

So i took Reagan in for her 2 month check up. I was supposed to get her some immunizations, but she has been sick - AGAIN - so i told them to pass on it. Well, seeing as she was born 6lb 7oz and realizing she had gained some weight i thought she would be around 9lbs. Well, i was wrong. She was 12lbs 3oz and 23inches long!!! Holy cow. I asked the nurse if that was a normal weight gain and she just looked at me, kinda smiled, and then told me to adjust her so we could get her height. What does that mean??? So when the doctor came in he said, "well...you have a healthy child." He said that she's taller than 80% of the girls her age and heavier than 85%!! At least we know she's not starving. Geesh.
