Milestones for an 18-Month-Old Child - Topic Overview
Children usually progress in a natural, predictable
sequence from one developmental milestone to the next. But each child grows and
gains skills at his or her own pace. Some children may be advanced in one area,
such as language, but behind in another, such as sensory and motor
Milestones usually are categorized into five major
areas: physical growth, cognitive development, emotional and social
development, language development, and sensory and motor development.
Most children by 18 months of
- Gain weight and grow at a steady but slower
pace than during their first 12 months of life. Between 12 and 24 months of
age, expect your child to gain about
3 lb (1.4 kg) to
5 lb (2.3 kg), grow an average
of 3 in. (7.6 cm) to
5 in. (12.7 cm), and gain about
1 in. (2.5 cm) in head
circumference (the measurement around the top of the head).
starting to lose the "baby" look. Your child, who is now in fast motion much of
the time, gradually adopts a leaner frame. Although your child's head is still
large in proportion to the rest of his or her body, by 18 months of age, the
face is not as "chubby." People may comment that he or she is starting to look
like a "little boy" or a "little girl."
- Get their first molars.
They may also get their canine teeth (also called "eye teeth"). See a picture
of the typical order that baby teeth come in .
not nap as much in the morning or give up this nap time completely. But they
still need to sleep about 13 to 14 hours in a 24-hour period.
Thinking and reasoning (cognitive development)
children by 18 months of age:
- Have developed a sense of self, the ability to
see themselves as separate from others. They can now imagine a threat and often
cling to parents and become fearful of strangers.
- Can usually find
an object that they watch you move from one place to another. For example, you
may hide a teddy bear under a blanket. After your child finds the teddy bear by
removing the blanket, he or she will find it again after watching you move it
under a pillow on the couch.
- Starts to play pretend. Usually it
will be one pretend act at a time, such as giving a stuffed animal a "drink"
from a toy cup. (By 24 months, he or she may act out a whole process, such as
getting "baby" ready for bed.)
- Can point to a body part. For
example, when you ask "where's your tummy?" your child will point to it.
