Child Development

As children grow older, they develop in several different ways. Child development includes physical, intellectual, social, and emotional changes.

Children grow and mature at very different rates. It's hard to say what "normal" is. There can be big differences in height, weight, and build among healthy children. Diet, exercise and genes are all factors. Some children begin puberty or are close to it before they are teenagers.

Children start to become more independent from their parents. They may rebel. They also look outward - to their friends, who are usually of the same sex. Peer approval becomes very important. Your child may try new behaviors to be part of "the group." This can also be the time that parents or teachers recognize learning disabilities or behavioral problems in children. These problems can get worse as time goes on, so it is important to get help early.

Learning Disorders

Also called: Learning differences, Learning disabilities

Learning disorders affect how a person understands, remembers and responds to new information. People with learning disorders may have problems

  • Listening or paying attention
  • Speaking
  • Reading or writing
  • Doing math

Although learning disorders occur in very young children, they are usually not recognized until the child reaches school age. About one-third of children who have learning disabilities also have ADHD, which makes it hard to focus.

Evaluation and testing by a trained professional can help identify a learning disorder. The next step is special education, which involves helping your child in the areas where he or she needs the most help. Sometimes tutors or speech or language therapists also work with the children. Learning disorders do not go away, but strategies to work around them can make them less of a problem.
