Despite their limitations, developmental screening tests can provide useful information. Early recognition of a problem can help prevent or reduce disabilities that some children with developmental difficulties might otherwise face. A child is thought to have what’s called developmental delay if she shows a consistent pattern of slow progress in one or more areas. This assessment should not be based solely on the results of developmental screening tests. In most cases, the child will be referred to a pediatric developmentalist, neurologist, audiologist, or other specialist for more detailed testing and evaluation.

In some cases, an underlying health problem is the cause of a child’s developmental delay. If such a problem exists, it’s important to identify it promptly because early treatment of some of these conditions may prevent or lessen the likelihood of long-term disability for the child. However, in most children with developmental delay, no specific underlying medical condition or cause can be found. But these children and their families can also benefit significantly from early identification of the delay.

Specially designed infant-stimulation programs, assistive devices and equipment, and other therapies have a good chance of improving a child’s developmental outlook if they’re started in the early years when the child’s brain is still growing rapidly and before potential complications of the condition occur. Early identification of the delay can also help parents adjust their expectations for the child appropriately and be more effective in helping the child reach his potential.

How quickly or how slowly your child develops is largely dependent on preprogrammed genes. As long as he is otherwise healthy and receives adequate environmental stimulation, proper nutrition, and lots of love and affection, there is probably little else you can (or should) do in an attempt to “speed up” or enhance his development. In fact, trying to prod a young child into doing something he is not developmentally capable of can be a frustrating experience for both child and parent, and it can even undermine a child’s motivation and self-esteem. However, a basic understanding of your child’s developmental progress can still be helpful.

First, it can be reassuring to know that your child is on track developmentally because this serves as a key measure of your child’s overall health. Second, understanding where your child is developmentally can help you decide which toys, games, and types of play would be most appropriate and enjoyable for your child.
