1. Make eye contact. Take advantage of those brief moments when your newborn's eyes are open, and look right into them. Infants recognize faces early on -- and yours is the most important! Each time he stares at you, he's building his memory.
2. Stick out your tongue. Studies show that newborns as young as 2 days old can imitate simple facial movements -- it's a sign of very early problem solving.
3. Let him reflect. Have your baby stare at himself in the mirror. At first, he may think he's just eyeing another cute kid, but he'll love making the "other" baby wave his arms and smile.
4. Make a difference. Hold up two pictures about 8 to 12 inches away from your baby's face. They should be similar but have one small difference (perhaps a tree is in one but not the other). Even a young infant will look back and forth and figure out the distinguishing features, which sets the stage for letter recognition and reading later on.
5. Blab away. All you may get is a blank look, but leave short pauses where your baby would speak. Soon she'll catch on to the rhythm of conversation and start filling in the blanks.
6. Go gaga. Your baby really tunes in to your silly cooing and high-pitched baby talk.
7. Sing a song. Learn as many tunes as you can, or make up your own verses ("This is the way we change your diaper, change your diaper, change your diaper . . . "). Play Bach, the Beatles, or Britney Spears. Some research suggests that learning the rhythms of music is linked to learning math.
8. Clue him in. When you announce, "I'm going to turn on the light now" before flipping the switch, you're teaching cause and effect.
9. Tickle her toes. In fact, tickle her all over. Laughter is the first step in developing a sense of humor. And playing games like "This little piggy" (finish by tickling her under the chin) or "I'm gonna get you" teaches your child to anticipate events.
10. Be a funny face. Puff up your cheeks, and have your toddler touch your nose. When she does, poof! Have her pull your ear, and then stick out your tongue. Make a funny noise when she pats your head. Keep to the same routine three or four times, then change the rules to keep her guessing.
11. Joke around. Point to a photo of Uncle Frank, and call him "Mommy." Then tell your child that you were being silly and laugh at your "joke" to build her budding sense of humor.
Bond Every Chance You Get
12. Breast-feed, if possible. And do it for as long as you can. It's a fact that schoolkids who were breast-fed as infants have higher IQs. Plus, nursing is a great time to bond with your infant by singing, talking, or simply stroking that delicious baby hair.
13. Make the most of diaper time. Use moments on the changing pad to teach body parts or pieces of clothing. Narrate to help your baby learn to anticipate routines.
14. Turn off the tube. Your baby's brain needs one-on-one interaction that no TV show, no matter how educational, can provide.
15. Don't forget to give it a rest. Spend a few minutes each day simply sitting on the floor with your baby -- no music, bright lights, or playful tricks. Let him explore, and see where he takes you.
Get Physical
16. Be a playground. Lie down on the floor, and let your baby climb and crawl all over you. It's cheaper than a jungle gym and lots more fun! You'll help boost her coordination and problem-solving skills.
17. Build an obstacle course. Boost motor skills by placing sofa cushions, pillows, boxes, or toys on the floor and then showing your baby how to crawl over, under, and around the items.
18. Shake it up, baby. Teach her to twist and shout, do the funky chicken, or twirl like a ballerina.
19. Play "follow the leader." Crawl through the house, varying your speed. Stop at interesting places to play.
20. Now follow his lead. As your toddler gets older, he'll stretch his creativity to see if you really will do everything he does, like make silly noises, crawl backward, or laugh.
Explore New Surroundings
21. Share the view. Take your baby on walks in a front carrier, sling, or backpack, and narrate what you see -- "That's a little dog" or "Look at those big trees!" or "Did you hear that fire engine?" -- to give your baby endless vocabulary-building opportunities.
22. Go shopping. When you need a break from your song and dance, visit the supermarket. The faces, sounds, and colors there provide perfect baby entertainment.
23. Change the scenery. Switch your toddler's high chair to the other side of the table. You'll challenge his memory of where things are placed at meals.
Play and Be Silly
24. Surprise her. Every now and then, delight your baby by gently blowing on her face, arms, or tummy. Make a pattern out of your breaths, and watch her react and anticipate.
25. Practice three-card monte. Grab a few empty plastic food containers, and hide one of your baby's small toys under one. Shuffle the containers, and let him find the prize.
26. Play peekaboo. Your hide-and-seek antics do more than bring on the giggles. Your baby learns that objects can disappear and then come back.
27. Pick it up. Even if it seems like your baby repeatedly drops toys off her high chair just to drive you nuts, go fetch. She's learning and testing the laws of gravity. Give her several pieces of wadded-up paper or some tennis balls, put an open bucket under her seat, and let her take aim!
