When 2-year-old Greyson sings happy birthday, he really goes all out. He's giving us quite the performance as he belts out the words and does a little dance along with the song.
Next, it looks like it's naptime for little Caiyo. He chooses an unusual spot to take a snooze, though!
Then, baby Harper is dancing with her dad and it's almost too cute to handle. What an adorable dance duo.
