Nina had her 1 year checkup. She's 16 lbs 12 oz (3rd percentile) and 28 inches tall (10th percentile). Her head circumference is in the 50th percentile. The doctor is happy with her size, growth, and development. Most of the data that doctors use is based on formula fed babies, who start out small and get fatter, as opposed to breastfed, who start out fat and slim out. We think Nina is juuust right, and we're happy the doctor does, too.
