How long can a newborn stay awake?

Newborns (0 to 4 weeks) can typically only handle 30 to 60 minutes of awake time before becoming overtired. By 2 to 3 months, this expands to 60 to 90 minutes.

What are the classic signs that a baby is overtired?

Signs of an overtired baby include: arching back, clenched fists, frantic crying, eye rubbing, yawning, turning away from eye contact, and extreme difficulty settling to sleep.

What are the AAP Safe Sleep guidelines (The ABCs of Sleep)?

The American Academy of Pediatrics recommends: A (Alone - no loose blankets, pillows, or toys in crib), B (on their Back for every sleep), and C (in a safety-approved Crib or bassinet on a firm, flat surface).
