Growth and Development, Ages 12 to 24 Months - What to Expect
General growth and development
Children usually progress in a natural, predictable sequence from one developmental milestone to the next. Children who are 12 to 24 months of age make gains in five major areas: physical growth, cognitive abilities, emotional and social development, language skills, and sensory and motor development.
- Physical growth, although slower than in the first year of life, continues at a steady pace. In the second year, toddlers gain an average of 3 lb (1.4 kg) to 5 lb (2.3 kg) and grow an average of 3 in. (7.6 cm) to 5 in. (12.7 cm) Also, teething continues with the eruption of the first molar teeth .
- Cognitive development is a child's increasing skill at thinking, learning, reasoning, and remembering. A toddler begins to recall past events, understand symbols, imitate, imagine, and pretend.
- Emotional and social development during the second year is characterized by strong emotional attachments to parents. Your child may feel uneasy and cry when he or she is separated from you. During this time, toddlers typically develop two conflicting feelings: wanting both independence and reassurance from their parents. Although their emotions change often, toddlers' personalities and temperament are becoming more defined.
- Language development rapidly progresses. At 12 months, many children can say a few words. And they jabber often. At 15 to 18 months, a typical toddler understands 10 times more than he or she can put into words. Speech begins with one- or two-syllable words, such as "mama." This progresses to short two-word sentences, such as "no peas" or "walk dog," sometime between 18 and 24 months. By 24 months, most toddlers can say at least 50 words.
- Sensory and motor skills advance as your toddler starts walking and moving around. Climbing, running, and hopping soon follow.
Although most children reach milestones, such as walking and talking, by a specific age, it is important to remember that development happens at an individual pace. Also, many children tend to make progress in one area, such as talking, while another skill, such as walking, levels off. If your child has a slight delay in an area, it does not always mean there is a problem. But be sure to talk to your doctor anytime you have a concern.
