How does my child grow between ages 12 and 24 months?

Incredible changes occur between your child's first and second birthdays, a period known as the toddler years.

Growth and development in all major categories are largely a result of rapidly forming synapses, or connections between brain and nerve cells.

Areas of change include:

Physical Development

Expect your child to grow about 3 in. (7.6 cm) to 5 in. (12.7 cm) and gain between 3 lb (1.4 kg) to 5 lb (2.3 kg) .

Cognitive Development

Your child will begin to recall prior events, understand symbols, imitate, imagine, and pretend.

Emotional & Social Development

Toddlers form strong emotional attachments and often experience anxiety when separated from loved ones. As this anxiety fades, the toddler typically develops strong feelings of independence mixed with an intense need for reassurance.

Language Development

At 15 to 18 months, a typical toddler understands 10 times more than he or she is able to put into words. Gradually, more words form, and by 24 months a typical toddler has a 50- to 100-word vocabulary. However, normal language development can vary widely between individual children.

Sensory & Motor Development

Changes in the brain make it possible for the toddler to gain the control and coordination necessary to become a steady walker. Climbing, running, and jumping soon follow.
