Bucky and you are good friends, you’re both Avengers and met when Steve saved him and brought him home.
Your partner left you when he found out you were pregnant, leaving you to do it all on your own. But Bucky stepped in, helping with everything you needed, coming along to your appointments, building a nursery, and eventually he helped you through the birth as well.
You fell asleep a couple of hours ago, you had been so exhausted after being awake with the baby all night. You wake up with a start when you realise you hadn’t heard your baby in a while, you panic slightly when you can’t find the baby in the crib. Worriedly you search the tower, only to find the baby doing tummy time on Bucky’s chest, the baby makes adorable noises. Bucky looks up with a smile, one hand on your baby’s back. “Hey doll. You sleep well?” He asks, looking completely at ease with your baby, a stark contrast to when she was a newborn.
