Look at my chunky boys!! We had a check-up at the doctors today. Connor was 13lbs 2oz and 22 inches long. Zander was 12lbs 14oz and 22 1/2 inches long. Yes, Connor is bigger. He has fat rolls on his legs and a cute pot belly. Zander burns more calories than Connor because he cries so much more. They are only in the 10th percentile for a 4 month old, but they are growing steadly and gaining weight.
