If your child looks exhausted at 5pm but suddenly turns into a tiny nightclub gremlin at bedtime, you are not imagining it.
Sometimes overtired children do not get calmer.
They get wired.
That “second wind” can happen when your child has pushed past their ideal sleep window and their body starts working extra hard to keep them going. Instead of looking sleepy, they may become silly, emotional, hyperactive, restless, rough, loud or suddenly very determined to do absolutely anything except sleep.
Before assuming they are “not tired yet”, it can help to look at what happened in the lead-up to bedtime.
A few things to check:
Were they already showing tired signs earlier?
Has bedtime slowly crept too late?
Have screens been used close to bedtime?
Was there rough play or lots of stimulation before bed?
Was the wind-down window long enough?
Have naps changed recently?
Did they have a big emotional day?
Wired does not always mean wide awake.
Sometimes it means their little body needed sleep earlier, but missed the window.
A calm, predictable wind-down and slightly earlier bedtime can make a big difference when overtiredness is part of the picture.
