Peekaboo is a game similar to hide and seek, but played with babies. In the game, one (child, teenager, or adult) hides their face, pops back into the baby's view, and says — to the baby's amusement — Peekaboo! I see you!
Isn't this adorable? Ashlee plays Peekaboo just like my 11-month-old son: By covering just the one eye. I'll tell Ashlee the same thing I tell my kid: That's cheating, buddy, and if you keep it up, you're going straight to hell, where Satan gouges out your eyes out if you cheat.
