So play often, and get those synapses firing!

Step-by-Step:

• Cover your face with your hands and ask, "Where's Mommy (or Daddy)?" Wait about three seconds before taking your hands away. Your baby will laugh with joy when he or she sees your face again.
• Hold a blanket, a cloth diaper, or a napkin between you and your baby and ask, "Where's (baby?s name)?" Reveal his or her face and say, "Peek-a-boo, Mommy or Daddy sees you!" (Use proper names whenever possible since babies don't yet understand pronouns.
