Give two examples of developmental red flags in infancy that warrant further assessment.

• A. Not rolling by 6 months; lack of social smile by 2 months; persistent language delays.
• B. Advanced walking by 7 months; excessive talking.
• C. Always meeting milestones on time; high levels of alertness.
• D. Preferring to sleep quiet and long.

Answer: (A)

Red flags in infancy show delays across motor, social-emotional, and communication domains that suggest a need for further evaluation. Not rolling over by 6 months signals a motor development delay in gross movement skills, since rolling is a typical early milestone. Lack of a social smile by 2 months points to a social-communication concern, as a social smile is usually present early and helps gauge social engagement. Persistent language delays indicate ongoing challenges with communication development, which can be one of the earliest signs of broader developmental concerns. When multiple domains show delay, the pattern strengthens the need for assessment and possible early intervention.

The other scenarios describe typical or non-problematic patterns. Advancing motor skills early or excessive talking are not standard red flags in infancy. Meeting milestones on time and high alertness can indicate typical development, while a quiet, long sleep pattern is not by itself a red flag for developmental delay.
