Toddlers: Child Development

Developmental Milestones for Toddlers 1-2 Years of Age

During this time, your child is becoming increasingly more mobile, and aware of himself and his surroundings. Her desire to explore new objects and people is also increasing. During this stage, your toddler will show greater independence, begin to show defiant behavior, recognize himself in pictures or a mirror, and imitate the behavior of others, especially adults and older children.

Your toddler will also be able to recognize names of familiar people and objects, form simple phrases and sentences, and follow simple instructions and directions.

Child Safety First (Toddlers 1-2 Years of Age)

As your child is becoming increasingly mobile, his ability to encounter more dangers is increasing as well. Here are a few recommendations to help keep your growing toddler safe.

  • Block off stairs with a small gate or fence. Lock doors to dangerous places such as the garage or basement.

Developmental Milestones for Toddlers 2-3 Years of Age

Because of your child's growing desire to assert her independence, this stage is often called the "terrible twos." However, this can be an exciting time for you and your toddler. He will experience huge intellectual, social, and emotional changes that will help him to explore his new world, and make sense of it.

During this stage, your toddler will be able to follow two- or three-phrase commands, sort objects by shape and color, imitate the actions of adults and playmates, and express a wide range of emotions.
