[When coworkers throw out adjectives to describe Natasha Romanova 'motherly' usually isn't one of them. Children aren't her forte and she normally avoids them like the plague - they're .. sticky, they cling, they ask stupid questions and stick their noses into things that shouldn't be meddled with (who does that sound like?) and -- she can't take care of a child and do her job correctly.
Imagine her dismay when she woke up on her third day in Wonderland with a toddler who looked like her miniature curled up next to her. At first, she thought it was a practical joke.
A full twenty-four hours later, it'd become abundantly clear that no one was joking and that taking care of the
brat girl was her responsibility alone. She'd set the child down for half a second so that she could take a shower and off the baby had toddled to go and scrape her elbow - leaving Natasha with an identical scrape. That was no joke, and didn't make any sort of logical sense.
Neither did the fact that the kid had been screaming non-stop for the last 30 minutes, despite being fed, changed, bathed and rested (none of which Natasha was). Out of patience, out of her mind, she did the only thing she could think of, the only thing she thought might work -- she began to hum and after a few minutes, she actually began to sing quietly and in Russian.
She didn't notice that her video was on.
It wasn't a fancy song and her voice wasn't good, necessarily. It was obvious she didn't sing a lot. At first, she could barely be heard over the wailing of a very, very displeased redheaded toddler who Natasha struggled to hold in her arms, awkwardly trying to keep from dropping her. But as she kept singing, louder, the toddler slowly began to quiet and then coo, settling in her arms and eventually dropping off to sleep.]
