From birth to five years of age, height and weight are not the only developmental milestones we should be tracking. Other important milestones include how a child speaks, plays, acts, and learns. For children with autism, early detection of developmental delays it critical. With early detection and intervention, children with autism are more likely to become enrolled in mainstream kindergarten classes, gain the skills needed to increase social opportunities, and reach their full potential throughout their lifetime.

It is not uncommon for parents and family members to become concerned when their baby or toddler does not seem to be developing normally —”He hasn’t rolled over yet,” or “She has not said her first words yet” or “the little girl next door is already walking.” And while it’s true that children develop differently, at their own pace, and that the range of what’s “normal” development is quite broad, it’s hard not to worry and wonder.

If you think that your child is not developing at the same pace or in the same way as most children his or her age, it is often a good idea to talk first to your child’s pediatrician. Explain why you are concerned. Tell the doctor what you have observed with your child. Your child may have a disability or a developmental delay, or he or she may be at risk of having a disability or delay. You can also get in touch with your community’s early intervention program, and ask to have your little one evaluated to see if he or she has a developmental delay or disability. This evaluation is free of charge and will not hurt your child. The evaluation looks at his or her basic skills and, based on that evaluation, your child may be eligible for early intervention services designed to address your child’s special needs.
