A Mother of an 11-Month-Old Is Concerned About Her Baby

A mother of an 11-month-old is concerned about her baby not walking and states that his older brother was walking at 10 months. The nurse's response, based on knowledge of normal development, should be:

A) "Your son may be somewhat slow developmentally. You might have him evaluated by a neurologist."
B) "The rate of development can be very different from one child to another, even among brothers and sisters."
C) "Don't worry. Children can be perfectly normal and not walk until they are 2 years of age."
D) "It's hard to predict when a child will walk. Some walk before they are able to crawl or sit alone."
