According to the National Screening Committee, by what age should all babies be formally reviewed?

The correct answer is 8 weeks because the National Screening Committee recommends that all babies should be formally reviewed by this age to ensure they are developing appropriately and to identify any potential health issues early on. This review typically includes physical examinations and assessments, which are crucial for monitoring growth, nutrition, and overall well-being. Early detection of health concerns can lead to timely interventions, which can significantly influence a child's long-term health and development, aligning with best practices for neonatal care. The 8-week mark is strategically chosen as it aligns with the routine healthcare visits that new families are encouraged to attend, facilitating access to necessary screenings and assessments.
