What if Peter's metabolism burnt through his energy from sleeping the same way it does food.
So for Peter a whole 6 hours of school is like 18 hours, so he takes little naps.
When Peter goes to Tony's for his internship, Tony is still in a meeting, and Peter is SO tired and Tony's MIT hoodie is on the couch.
Tony gets back and is greeted by the sight of an adorable sleep rumpled Peter with sweater paws making grabby hands for cuddles, because Tony is warm.
Tony and Peter curl up on the couch while Tony does paperwork on his StarkPad, although this devolves into Tony watching Peter sleep.
When Peter wakes up, his sweater paws are rubbing his eyes, his face is flushed, and curls are ruffled, and he smiles so sweetly when he sees Tony.
Tony just loses it at how cute Peter is and kisses him.
This becomes tradition, every afternoon Peter will steal one of Tony's hoodies/sweatshirts and just curl up next to Tony, or on Tony's lap, and when he wakes up Tony covers his face in little kisses.
It’s their tradition for the rest of their lives together.
