Chrissy Teigen has shared pretty much every adorable moment of her daughter Luna’s little life. From her first public photo, her first (controversy-sparking) Halloween costumes, even her first attempted prank. Now, get ready to squeal, as baby Luna has started talking and it’s just so wildly cute.

Chrissy Teigen and baby Luna

While we don’t know if this is Luna’s very first word ever or just her first time saying this particular word, it really doesn’t matter, because it will simply melt your heart and put a smile on your face.

Taking to Instagram, proud mama Chrissy Teigen shared a short video of her baby girl eyeing a kitty nearby. While Luna’s dad, John Legend, urges the little one on with the help of Teigen, Luna eventually pipes up with a clear, “Cat!” (or rather, “Caa!”). So sweet!

We can’t wait to see what Luna tackles next.

Do you know what your first word was? What was your baby’s first word? Let us know @BritandCo!
