The Growing Child: 1-Year-Olds 

After a baby's first birthday, the rate of growth begins to slow down. The baby is now a toddler and is very active.

What can my baby do at this age?

As your baby continues to grow, you will notice new and exciting abilities that develop. While babies may progress at different rates, the following are some of the common milestones your baby may reach in this age group:

  • Walks alone by 15 months, then begins to run

  • Can stop, squat, then stand again

  • Sits down on small stool or chair

  • Climbs stairs while holding on

  • Dances with music

  • Plays with push and pull toys

  • Can build towers out of blocks

  • Throws a ball overhand

  • Puts two- to three-piece puzzles together

  • Scribbles with crayon or pencil and may imitate drawing a straight line or circle

  • Mostly feeds self with fingers

  • Begins to feed self with spoon

  • Drinks well from cup

  • Can help with dressing and may be able to undress simple clothes (i.e., clothes without buttons or zippers)

  • First molar (back) teeth appear

  • Takes one afternoon nap

  • May sleep 10 to 12 hours at night

What can my baby say?

Speech development is very exciting for parents as they watch their babies become social beings that can interact with others. While every baby develops speech at his or her own rate, the following are some of the common milestones in this age group:

  • Imitates animal sounds and noises

  • At one year, says four to six simple words

  • At 18 months, says 10 to 15 words

  • By 18 to 24 months, uses simple phrases or two-word sentences (such as, "Mommy up")

  • By 2 years, says 100 or more words

  • Asks "What is…?"

  • Uses negative phrases such as "No want"

What does my baby understand?

By about 18 months of age, children begin to understand symbols—the relationship of objects and their meanings. While children may progress at different rates, the following are some of the common milestones children may reach in this age group:

  • Waves bye-bye and plays pat-a-cake

  • By 18 months understands one-step questions and commands such as "Where is the ball?"

  • By 24 months understands two-step questions and commands such as "Go to your room and get your shoes."

  • Understands object permanence (a hidden object is still there)

  • Understands the cause and effect relationship better

  • Likes to explore drawers and boxes to see what is inside

  • Make-believe play increases (i.e., may imitate housework or feed a doll)

  • Recognizes own face in mirror

  • Can point to body parts (i.e., nose, hair, eyes) when asked

  • Begins to understand use of certain objects (i.e., the broom is for sweeping the floor)

  • May ask for parent's help by pointing

How does my baby interact with others?

As children begin to walk, they may begin to show independence and will try to walk further away from the parent, but will return. Separation anxiety and fear of strangers may lessen, then return at about 18 months. While every child is unique and will develop different personalities, the following are some of the common behavioral traits that may be present in your child:

  • Plays along side others without interacting, called parallel play

  • May begin clinging to parents around 18 months

  • May begin to say "no" more frequently to commands or needs

  • May have temper tantrums

  • May use a blanket or stuffed animal as a security object in place of the parent

How to help increase your baby's learning and emotional security

Consider the following as ways to foster the emotional security of your 1-year-old:

  • Give your child toys that can be filled and emptied and toys for imaginary play.

  • Give your child simple two- to six-piece puzzles and balls of all sizes.

  • Help your child build towers of blocks.

  • Encourage your child to "help" you with household tasks.

  • Give your child paper and large crayons to scribble and draw.

  • Talk to your child with clear simple language about what you are doing.

  • Use the correct names for objects, even if your child does not. For example: your child might say "wa-wa," and you say "Water, that is right."

  • Expand your child's sentences. If your child says, "Want cookie," you say, "Do you want another cookie?"

  • Read to your child every day using picture and story books.

  • Feed your child at family mealtimes.

  • Provide consistent firm, appropriate discipline without yelling or hitting.
