An 18-month-old child is evaluated for developmental delay. He has absent speech (no words), can walk independently (achieved at 14 months), can build a tower of 2 cubes, and uses a spoon with spillage. Which developmental domain is MOST delayed relative to expected milestones at 18 months?

• A Language/Communication — 18 months minimum is 6–10 words and pointing ✓
• B Gross motor — walking should be present by 15 months
• C Fine motor — 2-cube tower is within normal limits
• D Social/Self-care — spoon use is below expected for age

Explanation

At 18 months, expected language milestones include 6–10 words with meaning and pointing to indicate wants. Absence of any meaningful words (no words at 18 months = language red flag) represents the most severely delayed domain. Gross motor: independent walking achieved at 14 months is within normal limit (limit 15–18 months; by 18 months all children should walk). Fine motor: 2-cube tower is expected at 15 months (3–4 cubes by 18 months), so slightly delayed but not as dramatically. Spoon use with spillage is appropriate for 18 months. Language delay is the most significant finding requiring urgent evaluation.
