It was one of those days were no one was able to watch little (Y/N). Clint was out on a mission with Natasha, Bruce was giving a speech at some Science Convention, Steve was out with Bucky, and the twins were busy in training, so that left Tony. Now, Tony was NOT thrilled being stuff with (Y/N). He just wanted to play with his technology and suit. So he got a playpen, and stuck (Y/N) into it.

After a few hours of non-stop work, Tony felt a tug at his pant-leg. He looked down only to see (Y/N)! "How the hell did you get out?!" He asked. She only gave him a toothless giggle. Tony sighed and picked you up. "Your annoying like your father." He muttered.

The rest of the day Tony kept (Y/N) close by, in a tiny box. But don't worry! It had holes.
