We went for Avery's 18 month check up today. She has met all of her milestones, and the doctor said that she was very advanced :) Here's her stats:
weight: 19 pounds 14 ounce (33%)
height: 31.75 inches (50%)
head circumference: 75%
Yes, we're still under 20 pounds and technically should be riding rear-facing in the car. Hilarious. And, if you have ever been around this child, you know that she eats like she's never been fed before!
