Feedback:
The physical features of a child with Down syndrome are distinctive, and therefore the condition usually is apparent at birth. These features include growth failure and a small and rather square head. There is a flat facial profile, small nose, and somewhat depressed nasal bridge; upward slanting of the eyes; small, low-set, and malformed ears; and a large, protruding tongue. The child's hands usually are short and stubby, with fingers that curl inward, and there usually is only a single palmar crease (simian crease).
