This went down just a few minutes ago in our kitchen as I handed the baby to my husband after dinner:
Me, jokingly: “Baby, barf on Daddy!”
Baby: *BARF*
Daddy: “That’s not funny! You’re gonna get it one day – he’s gonna barf in your MOUTH!”
Me: “Hah! He already HAS!”
Daddy: “Crud, you’re right…never mind…”
