Watch for overtiredness

Today's lesson

An overtired baby produces cortisol and adrenaline, making it harder to fall asleep and stay asleep. If bedtime is a battle, try moving it 15–20 minutes earlier for a few nights.

Your action steps

• Look for red eyebrows, staring, or hyperactivity as tired signs.
• Move bedtime earlier if naps were short.
• Don't wait for crankiness — that's usually too late.
