Here's everything I remember
-Tony hasn't slept for days tinkering in the lab
-Pepper and Happy (maybe Harley too) tries to get him to sleep
-Peter comes into the lab and said he was had a nightmare and went looking for Tony in his bedroom but he wasn't there and starts crying
-The other two/three feels bad for him and wants to comfort him
-Tony picks him up and takes him back to bed
-Peter mouths you're welcome as Tony carries him out of the lab
If you know what this cute fic is, please let me know!
