The "Lip Sync Battle" host shared an adorable clip of the tot on her Instagram on Thursday, June 20, showing him sitting in his high chair alongside her mother Vilailuck.
As Vilailuck asked Miles "Do you love Yay?", the little boy chirped back, "Yeah!" And for each question asked of him by his grandma, such as "You love Mommy? You Love Dada?", Miles replied with an enthusiastic "Yeah!"
Captioning the video, Chrissy wrote, "When your first word is 'yeah!' "
Adding a comment, Chrissy, who is also mother to three-year-old daughter Luna with John, wrote, "Luna's first word was 'no'. They're exactly us."
