Hang on tight! From the moment you bring your baby home from the hospital, he'll go through a whirlwind of developmental milestones. Enjoy these exciting baby "firsts" because infancy will be gone in a flash. Just remember that all babies are different, and your little sweet pea will have his own timeline for development. If you ever feel concerned about your baby's development, talk to your pediatrician.

First meaningful smile: 2 months

You may have seen glimpses of a tiny smile during your baby's newborn sleep, but at 2 months of age, your little guy will begin smiling with purpose. There's nothing better than those first happy coos when you play together.

First full night of sleep: 3-4 months

Hallelujah! Exhausted parents everywhere can expect their baby to sleep through the night at around 3 or 4 months of age. If you're still having trouble getting the sleep you need after this time frame, talk to your pediatrician about your concerns.

First giggles: 4 months

Peals of laughter from your baby will stick with you forever. Your baby will begin giggling and laughing at around 4 months of age, so be ready for hours of fun playing peekaboo and tickle games.

First time rolling over: 4-6 months

Some babies roll over at an age as early as 3 months, but you can reasonably expect your child to roll onto his tummy and back somewhere between 4 and 6 months. You can strengthen his "roll-over" muscles by offering plenty of tummy time.

First unsupported sit: 6-8 months

This is where the fun really begins! Once your baby sits unassisted, you can play together more easily with blocks and other baby toys. Not only that, but your baby will be able to start clapping, grabbing and eating finger foods once he masters the unsupported sit.

First pincer grasps: 8-9 months

Speaking of finger foods, your baby's awkward grab will turn into a coordinated pincer grasp between 8 and 9 months of age. This skill will allow him to use his pointer finger and thumb to pick objects up more easily.

First crawl: 8-9 months

Hold on, Mama! It's time to completely baby-proof the house when your baby is between 8 and 9 months old, because it won't be long before he starts crawling or scooting quickly throughout the house.

First pointing and waving "Bye-bye": 9 months

Your baby will understand symbolism by the time he's 9 months old, which means he'll start pointing to objects he wants from you. He'll also begin to wave, because he'll understand that waving is a symbol for hello and goodbye.

First pull-up to stand: 9-10 months

Once your baby masters the crawl, it won't be long before he can pull himself up to stand (although some babies skip right over crawling and move on to standing). Your child will use furniture to support himself until he can stand unassisted at around 11-12 months of age.

First words: 10-12 months

Your baby will string his random babbles into meaningful words when he's just shy of a year old. Usually, a baby's first words are "Mama" or "Dada," although he might surprise you with "no" or "more!"

First steps: 10-17 months

It's a whole new ballgame when babies make the switch from crawling to walking. Some babies take their first steps when they're as young as 10 months of age, but the average age when babies begin to walk is around 13 months. Don't be alarmed, though, if your baby is a little slower to develop, since some children don't walk until they're 17 months old.
