Question: A 6-month-old boy presents for a routine visit. A history of present illness obtained from his father reveals that his son has started babbling out random unintelligible words. He starts crying when the provider picks him up but stops when his father grabs him back. The patient can transfer a stuffed toy from one hand to another. His father says that he has now started to sit up unsupported. He recognizes his name and gives a social smile when the provider calls out to him. The father is distressed that he hasn't started crawling yet and is worried that his son may have some developmental disorder. His family history is significant for a 3-year-old sister who has a delay in language development. What is the best next step in the management of this patient? Need Assignment Help?
