The Overtiredness Trap
If you have spent any time on parenting social media lately, you have likely seen the warnings: “Don’t miss the sleep window!” or “An overtired baby won’t sleep!”. While overtiredness is a real factor to consider, it isn’t the ONLY factor.
I am seeing more and more parents who are so afraid of overtiredness that they are putting their babies to bed too early and without enough "sleep pressure". This leads to long periods of crying, protesting naps, short naps and frustration for the whole family.
Understanding Sleep Pressure vs. Boredom
For a baby to fall asleep and stay asleep, they need to build up enough sleep pressure throughout their awake window. If we rush them to the crib too early, they simply aren't biologically ready to sleep.
Often, what looks like a "tired cue" is actually just boredom. Did you know that a baby’s independent play window can be quite short? If they start to fuss after 10–15 minutes of solo play, they might just need a change of scenery or a new activity rather than a nap.
It is also common for children to have peaks and dips in energy (same as we so, but typically we reach for the coffee!). I often see babies looking tired around 1 hour after they wake in the morning and unless they are a Newborn this does not mean they are ready for a nap!
How to Tell the Difference
Use the guide below to determine if your baby is truly overtired or if they simply haven't been awake long enough.
Signs of Overtiredness:
Frequent yawning and eye rubbing.
Fussiness, crying, and irritability, especially when you try to soothe them.
Difficulty falling asleep or staying asleep.
Restlessness, squirming, or a tense body with clenched fists.
Hyperactivity (common in toddlers).
Arching of the back or stiffening of the limbs.
Difficulty focusing or becoming easily distracted.
Disrupted patterns, including short naps and night-time wake-ups.
Signs of Undertiredness:
Short naps, often lasting only 20 minutes or less.
Playing in the crib for longer than 20 minutes before finally falling asleep.
Frequent waking after only a short duration of sleep.
Struggling to fall asleep or "fighting" the nap despite looking tired.
Completely rejecting the nap by playing or crying off and on for the whole duration.
Waking up content from a short nap but lacking the stamina to make it to the next scheduled sleep time.
The 15 minute shift
Every baby is unique, and their sleep needs can change from week to week. If your baby is fussing in their crib for longer than 20 minutes, the solution might not be a shorter awake window.
Try extending the awake window by 15 minutes instead of shortening it.
That extra 15 minutes of activity helps build the necessary sleep pressure to help your baby fall asleep faster and stay asleep longer. By monitoring these cues consistently, you will better understand your baby's specific needs and can adjust their routine with confidence.
Final Thoughts and Tips
If your baby is showing tired/boredom signs before their nap is due, try changing their activity, taking them outside / to a window (daylight really helps us to stay awake!) If your baby is older and eating solids you could offer them a snack.
