The ages between 2 and 5 are often called the preschool years.
During these years, children change from clumsy toddlers into lively explorers
of their world. A child develops in these main areas:
grows and gains skills at his or her own pace. It is common for a child to be
ahead in one area, such as language, but a little behind in another.
Learning what is normal for children this age can help you spot problems
early or feel better about how your child is doing.
Routine checkups usually are scheduled several times during ages 2 to 5. These routine checkups
are called well-child visits. They are important to check for problems
and to make sure that your child is growing and developing as expected.
During these visits, the doctor will:
Well-child visits are a good time to talk with your doctor about any
concerns you have about your child's health, growth, or behavior. Between
visits, write down any questions you want to ask the doctor next time.
Call your doctor
anytime you have a concern about your child's physical or emotional health. Be
sure to call if your child:
It's important to learn about some of the behaviors you can expect during
these years of rapid change. Temper tantrums, thumb-sucking, and nightmares are
common issues in children this age. Knowing what to expect can help you to be
patient and get through the stressful moments.
The best thing you
can do for your child is to show your love and affection. But there are also
many other ways you can help your preschooler grow and learn.
Raising a preschooler can be challenging. What works or
is right for a 2-year-old may not be right for a 5-year-old. Taking a parenting
class can help you learn how to deal with issues as they arise. To find a class, ask your child's doctor or call a local hospital.

It's common for parents to have questions about their child's sleep, safety,
toilet training, and difficult emotions and behavior.
Preschool children need about 11 to 13 hours of sleep each day. Your child may go through
phases when he or she resists resting.
To help foster good sleep habits, you can:
help keep your child safe, it's very important to be aware of your
child's abilities and the environment, whether it is the home, a playground, or
a public place. These abilities change as your child grows and gains new skills.

Children ages 2 to 5 have many
intense emotions that they do not fully understand. As a result, expect your
young child to not always listen to you. Be patient, and do your best to be
consistent about setting limits to avoid some common
issues. These may include:
Each child learns to use the toilet at his or her own pace. Most children are ready for
toilet training when they are between 22 and 30 months
It can be hard to know
when to start toilet training. Your child's physical and emotional readiness is the most important aspect of the timing. You and your child will likely become frustrated if
you try toilet training before your child is ready.

reading to your child, and by letting your child play. It's also important to set boundaries and
Your relationship with your child will constantly change
as your child gains new skills and
develops independence. You can help your child through
each stage by looking at your relationship from time to time. Ask
If you are the parent or caregiver of children, it is also important
for you to:
Most children start kindergarten around age 4½ to 6 years.
It can be hard to know when your child is ready for school, but your local elementary school or preschool can help. Attending preschool or play groups can be a great way for children to build new skills and learn to interact with others.
Some of the tasks and behaviors that show that a child is ready for kindergarten are the following:
Although your child grows at
his or her own pace, be aware of signs of a
developmental delay. The earlier you identify a delay,
the better chance you have of getting the right treatment for your child that
can prevent or minimize long-term problems.
In general, talk to a
doctor anytime your child:
Routine well-child visits allow your
child's doctor to keep a close eye on your child's general health and
development. You also can discuss any concerns you have at these appointments. It may help you to go with a
list of questions(What is a PDF document?).
The doctor typically
Routine screening tests for
hearing and vision take place during the preschool years. A
specialist may do formal tests if your child's screening results are poor or if
there are any developmental concerns at ages 2 to 5.
will talk with both you and your child to get a sense of your child's mental,
emotional, and social development. Questions typically cover:
In addition to the above assessments, doctors usually ask
questions specific to a child's age.
Caring for your child's teeth is also important for your child's health. Schedule regular visits every 6 months or as your dentist recommends.
