First of all, this is TOO cute!
Chrissy and John were enjoying lunch with their daughter Luna on vacation when they saw a cat and decided to see if she could say the word "cat". Well, she did! She looked so accomplished and you hear Chrissy gasp in the background. A proud Mommy moment!
From her caption on Instagram, I can only assume that "cat" was Luna's first word! She's growing up so fast, time flies!
