Growth and Development, Ages 12 to 24 Months - What to Expect
Milestones by age
By 12 months (1 year) of age many children are walking without help or by holding onto furniture ("cruising"). Most children will have a few teeth and like to put almost anything in their mouths that they can. And many children will say a few words and practice a lot of sounds. Your child may like to "flirt" with you and other caregivers.
By 18 months of age-look out!-most children are walking with ease and anything within reach is fair game. Your child may like to press buttons, move handles, and turn knobs. You may notice your child pretending to "feed" a toy or a similar act that he or she sees. Most children understand 10 times as many words as they can say, including the names of some people, body parts, and objects. Many children can often point to an object in a book when asked.
By 24 months (2 years) of age most children feel excited, confused, and scared about their emerging independence. Temper tantrums may start happening regularly. Children may start thinking in more complex ways, such as recalling events that happened days earlier. A child's make-believe world gets bigger as he or she may have play "events" rather than just one act. For example, he or she may pretend to be a mommy or daddy and care for a baby by changing a stuffed animal's diaper and feeding it a bottle. Most children say at least 50 words and use two-word phrases. Not only can most toddlers walk, but they also can run-and go up and down stairs.
Babies who were born early (premature)
Until age 2, a child born prematurely (3 or more weeks early) will have growth and development milestones adjusted based on gestational age. To figure out your baby's adjusted (corrected) age, doctors subtract the number of weeks your baby was born early from his or her current age. For example, the corrected age of a 17-month-old baby who was born premature at 30 weeks is between 14 and 15 months.
