Baby won't sleep even though tired — overtired?

Overtiredness — the biggest enemy of baby sleep

In short: Yes, a baby that is TOO tired will sleep WORSE. It sounds paradoxical, but overtiredness releases stress hormones (cortisol, adrenaline) that make falling asleep harder.

Signs of overtiredness

Early tiredness signs (PUT THEM DOWN NOW!):

• Yawning
• Rubbing eyes
• Looking away, staring
• Pulling ears/hair

Late signs (already overtired!):

• Fussing for no reason
• Arching back
• Hyperactivity — seeming "wound up"
• Crying, inconsolable

Wake windows by age (THE GOLDEN rule)

When baby is ALREADY overtired

1. Low stimulation: Dark room, no toys, no stimulation
2. Movement: Stroller, car, baby carrier — movement helps overtired babies
3. White noise: LOUD (65-70 dB) — drowns out the inner restlessness
4. Body contact: Skin-to-skin, gentle rocking
5. Don't give up: It takes longer than usual — and that's okay

The prevention

Watch the CLOCK, not just the baby. If you know your 4-month-old gets tired after 2 hours, start the bedtime routine BEFORE — BEFORE the tiredness signs appear.
