Developmental delay refers to when a child does not reach the developmental milestones expected of children their age. Delays may occur in motor function, speech, hearing, or vision.
Of course, if a child was born premature and has a milestone delay of a month or so, that is perfectly normal. However, if delays are persistent or significant, they can indicate serious medical conditions.
It’s important to remember that each child develops at their own pace. So if your child doesn’t reach a certain milestone for that particular age, don’t panic or get anxious. Give it some time. If you are still worried about your child’s development, consult your pediatrician.
