Bobby Drake in X-Men Blue #2
Bucky babysitting your three y.o kid overnight because you have to go somewhere. You didn't want to go at first but you go anyway because you'll be back by morning. You come back the next morning to find them both passed out on the couch in a mess of limbs with your kid hogging the blankets. Kid's excuse: "I was scared of the dark, Mommy. Bucky was protecting me!"
