The Sweetest Baby Milestones

All milestones in Baby's first year are special, but some are especially sweet. Moments like smiling and blowing kisses are also worth tracking on your infant development chart. Find out when to expect these developmental milestones and more.

Development Milestones: What to Expect at 6 Months

It was a blah January evening, and I'd come home from work with a headache. I called my mom to say hi, then plunked the cordless phone down on the bed, between me and my 13-month-old daughter, Genie. Wearily, I closed my eyes and sighed.

"Hehwoe? Hehwoe?" I opened my eyes again—Genie was holding the receiver! "Uh-buh-dee-dah? Uh-huh. Bye-bye!" she chattered into it. My headache magically disappeared as I doubled over in laughter. Then, surprisingly, I welled up with tears, thinking what a big girl my little girl had suddenly become.

When you hear the phrase "baby milestones," you think of the developmental milestones your pediatrician checks off on your child's health record—first step, first word, yadda yadda. But the cute tricks your child suddenly springs on you are equally good evidence that her mind and body are growing fast. Here's a timeline of milestones for some of those "grab-the-camera" moments, and what they say about your baby.

1 to 8 months

Smiling

1 1/2 to 2 months
What parents could possibly forget the first time their infant intentionally flashes a gummy grin? These "social smiles" (as opposed to the fleeting grimaces infants make when they're gassy) are heartwarming, but they're also a sign that the parts of your baby's brain that control eyesight and muscle movements are booting up.

A smile also shows off your child's newfound social savvy. She's starting to understand the positive emotions a happy face conveys—and that making one can get her plenty of attention. Encourage her by smiling at her as often as you can and, of course, acting surprised and pleased when she smiles back.

Laughing

4 to 6 months
Laughter is instinctive, but it's also something your baby has to learn. By this age, he's heard other people laughing many times, and he's gained enough control over his vocal cords to realize it's something he can do too.

Don't be surprised if he laughs like Flipper at first, making a staccato "heh-heh-heh" and then a high-pitched squeak as he inhales. The reason: His larynx is still small and floppy, and he doesn't have good control over it. Savor this ultra-cute phase while it lasts. By his first birthday, his laugh will be sounding a lot more like your own.

Blowing Raspberries

4 to 6 months
Babies love to do the Bronx cheer, even when your favorite baseball team doesn't lose the playoffs. What gives?

It's part of learning how to talk. Your child is experimenting with different ways to move her lips and tongue: Sooner or later, she'll probably make a raspberry—and love it. (About 25 to 33 percent of all babies never do, though, and just go straight to babbling.) Go ahead and egg on your little blowhard, maybe with some raspberries of your own. It will encourage her to try other sounds, which is great practice for forming consonants, vowels, and—eventually—words.

Eating His Feet

4 to 8 months
Sooner or later, you'll probably find your baby happily sucking on his toes. Yes, this is strange, but it's still an important milestone. His hands aren't very coordinated yet, but he's jonesing to learn more about the objects around him. So he explores things by putting them in his mouth—including his own feet, once he's found them.

Besides promoting body awareness, toe-sucking is very satisfying and soothing to your little one. So don't discourage it; this phase generally passes on its own. (And don't be concerned if he never does this trick, by the way—not all babies do.)
