Mrs. Harmon, the mother of 18-month-old Bryce, is concerned that Bryce has not learned to speak very well. He has a limited vocabulary and seems content to point to the things he wants. Mrs. Harmon has read several child development books which indicate that Bryce should be in the stage of language learning. Mrs. Harmon fears that Bryce is not keeping up developmentally. Based on your understanding of the timing of developmental stages, my best advice is the developmental stage can be useful guidelines, but there is a range of normal development within stages.
