A 3-year-old girl presents for her regular check- up. Her mother reports that she is fully toilet trained, and that she can dress and undress with minor assistance. She speaks in full sen- tences, can name four colors, and can copy a simple circle drawing. What other milestone would this child most likely have reached since her last visit one year ago?
(A) Engages in cooperative play
(B) Has imaginary friend(s)
(C) Hops on one foot
(D) Reads
(E) Rides a tricycle
(F) Stacks five blocks
The correct answer is E. This is a typical well-child visit. Other milestones reached at approximately this age include stacking nine blocks, riding a tricycle, and beginning to en- gage in group play. Riding a tricycle at 3 years is easy to remember because a tricycle has three wheels. The number of blocks stacked between ages 2 and 4 years is about three times the child’s age in years; that is, a 2-year-old can stack six blocks, whereas a 3-year-old can stack nine blocks.
Answer A is incorrect. Engaging in coopera- tive play is achieved between 4 and 5 years of age.
Answer B is incorrect. Imaginary friends are typically present between 4 and 5 years of age.
Answer C is incorrect. Hopping on one foot is typical of a 4-year-old child.
Answer D is incorrect. Reading is most often learned at 5-6 years of age and older.
Answer F is incorrect. Children at 2 years of age can usually stack six blocks, whereas chil- dren at 3 years can stack nine blocks.
