Peekaboo is a simple game you play with babies and toddlers by hiding your face, then quickly uncovering it. Peekaboo is a good way to make a baby laugh.

When you play peekaboo, you cover your face or hide behind a barrier for a few moments, then reveal yourself again to the baby and say, "Peekaboo!" A variation on peekaboo is a hiding and revealing game in which you say, "Where's the baby?" and then "There's the baby!" Peekaboo is fun because babies are generally interested and amused by it, and it's good for the development of their cognitive — or thinking — skills.
