Witney Carson McAllister on Instagram: "You see yourself as a big 5-year-old now… but you’ll always be the baby who made me a mom. 😭 Leo, you make your mom and dad so proud. You are silly, fun, and so thoughtful, always considerate and kind to everyone. You have the biggest heart with so much love! You are the most incredible big brother. Jet looks up to you in every way, how lucky is he to have you as his older brother and protector. Watching you learn and grow is the greatest joy of our lives
