Teething pain, growing pain, yes,-running-into-a-wall-will-hurt- pain. These are all the things a parent signs up for when having kids.

In this society, parents also sign up for dealing with quirk pain when the time rolls around. Four whole years, they usually think. 'So much time to prepare'. And it is, but they as well have to be ready for it mentally.

A child getting their quirk is also a big emotional milestone. And it can happen anytime.

Any time. Yes, even at 4:00am. Not much time to decipher whether he woke up from training instinct or paternal instinct before he was pulling himself out of bed at the sound of... a clash? Crying? He was still tired as hell.

He didn't stop when he got to the door to your room, twisting the knob carefully enough not to be startling but with enough speed that if there was a problem, he'd be moving fast enough to be considered efficient.
