Your Baby's Development Between Two and Three Years

It's thrilling to watch your baby grow and develop, as they learn about you and the world around them. 

The information below shows some things your baby may be doing at two years of age and up. Keep in mind that every baby develops differently. Your baby may reach any of these milestones significantly before or after this age. Chances are, her development is proceeding perfectly normally.

SPEECH
Between two and three years: 

Vocabulary grows rapidly and child starts combining nouns with verbs to form three to four-word sentences 
Begins to use pronouns, such as "I" and "me," and other parts of speech 
May begin to ask "why" questions 
Pays attention to what others say, whether to him or to someone else

MOTOR SKILLS
Your baby's motor skills encompass all sorts of movement, from supporting her head, to crawling, to holding a crayon. 

Gross motor skills involve control of the large muscle groups active in kicking, crawling and walking, among other movements. Fine motor skills typically cover movement and manipulation of objects with the hands -- skills such as reaching, grasping, picking things up and pointing.
