Your Brilliant Baby in Week 2: Copying Mouth Movements

Try it out: When your baby is not drowsy, hungry, or active, but instead quiet and awake, come eight to 10 inches from his face and stick out your tongue. Keep it there. Wait. Stay right there and calmly wait—it'll happen.

Later, somewhere between four and six months, Baby will make "raspberries" by pursing his lips and blowing. And down the developmental road a bit, he'll copy other small behaviors (pushing buttons on the remote control, computer, and dishwasher) that you might overlook—and wish he would!
