A child can walk upstairs using alternate feet, ride a tricycle, copy a circle (not a cross), name 3 colors, give full name, and feeds herself with a spoon. She has stranger anxiety but can separate from parents briefly. The most likely developmental age corresponding to these milestones is:
- A 18 months
- B 2 years
- C 3 years ✓
- D 4 years
Correct answer: C. 3 years
Explanation
These milestones are characteristic of a 3-year-old: alternating feet on stairs (18 months uses both feet on one step), tricycle riding, copying a circle (not cross — that comes at 4 years), naming colors, giving full name, and spoon feeding with less spillage. Stranger anxiety peaks around 8–10 months but a 3-year-old still shows some stranger caution while being more socially engaged than a 2-year-old. Copying a cross and drawing a man with 2–4 parts appears at 4 years.
