Usually, there is an age range of several months where a child is expected to learn these new skills. If the normal age range for walking is 9 to 15 months, and a child still isn’t walking by 20 months, this would be considered a developmental delay (2 standard deviations below the mean). A delay in one area of development may be accompanied by a delay in another area. For example, if there is a difficulty in speech and language, a delay in other areas such as social or cognitive development may coexist.
It is important to identify developmental delays early so that treatment can minimize the effects of the problem. Parents who have concerns about their child’s development should consult the child’s physician, who, in turn, might make a referral to a developmental pediatrician, developmental psychologist or pediatric neurologist. The consultant can evaluate the child and recommend treatments and therapies that might benefit the child.
