It's 4:15pm and your kid just screamed at you about snacks.
This is the cortisol crash.
Your kid held it together all day at school. Followed rules. Stayed quiet. Managed transitions. Kept their body regulated.
Then they walk in the door and completely fall apart over something tiny.
Here's what's happening:
Cortisol (your body's stress hormone) builds all day. Masking, socializing, sitting still, following instructions — all of it requires regulation energy.
When they get home, that cortisol drops fast. And the crash feels awful. Irritable, emotional, exhausted, hungry, overstimulated, ready to explode.
They're not trying to ruin your afternoon. Their nervous system just spent 7 hours in overdrive.
What actually helps:
Buffer time. Don't ask about their day or start homework right away.
Protein snack. Blood sugar + cortisol crash = meltdown fuel.
Low-demand activities. Screen time, quiet space, movement, whatever helps them decompress.
Your calm. They're borrowing your regulation right now.
What doesn't help:
"Did you have a good day?"
Jumping straight into demands (homework, chores, activities)
"Why are you acting like this?"
The after-school crash is biology, not attitude.
Your kid isn't broken. The world just isn't built for their nervous system.
