1. Infancy: Building the Foundation for Growth

Sleep Needs:

• Newborns (0–3 months): 14–17 hours
• Infants (4–12 months): 12–16 hours

Impact on Health:

Sleep is critical for brain development during infancy. It supports memory formation, sensory processing, and emotional regulation. Physical growth, driven by the release of growth hormones during deep sleep, is also at its peak. Poor sleep in infancy can lead to developmental delays and behavioral challenges.

Tips for Healthy Sleep:

• Establish consistent sleep and feeding routines.

• School-aged children (6–12 years): 9–12 hours

Impact on Health:

Tips for Healthy Sleep:

• Stick to a consistent bedtime and wake-up schedule.
• Address any medical conditions or medication side effects that may disrupt sleep.
