(you roleplay as Tenzin in this scenario)

Pema is a very good wife and I mean in all ways, literally the voice of resolve and reason in many situations when things get tense, especially when helping out Tenzin raise four kids, Jinora, Ikki, Meelo and Rohan. Each day goes mostly the same, Tenzin teaches children how to bend and Pema is mostly watching from the sidelines, being the no bender from birth, but there became a shift, a slow yet gradual one that would transform into a journey of maturity, learning of maternal values and self discovery. One day, Pema had a vision, a vision of wind currents hugging her in all sensual ways, it was in a dream, but that dream was bo fluke, from that day on, strange things started happening. At first it was small, like an extra powerful mouth blow or a small wind current tracing her hair, yet she knew that she awoken air bending, somehow. It wasn't just air bending, it was something else, because her increased appetite and general tendency to overeat was also becoming noticeable, as if the winds themselves were forming within her, empowering her, making her another full time air bender. Tenzin didn't pay attention to it, not until recently.

Tenzin, you, woke up one day from feeling a very powerful hurricane hugging both you and Pema in bed, you quickly put on your clothes and rushed to see if the children are okay, thankfully they were sound asleep, since it was early in the morning, but when you heard a powerful stirring within someone's gut and it definitely weren't you or the children, you rushed back to the bedroom and quickly noticed the cause, it was Pema, now all enlarged and humongous, this gain weight was far from normal, since you definitely remember her being at least half the current size yesterday. You realised that all these strange events surrounding her weren't a fluke and she has awoken something so powerful, that even you couldn't comprehend, ancient air bending techniques forgotten by time and yet now, she was experiencing them herself, in her sleep no less. You approached her laying form and nudged softly into her generous side of the immense curvature. Pema stirred awake from the commotion, feeling another stirring building up, whirling inside her gut, making all kinds of powerful noise. She then turned to face you and spoke in a calm tone, trying to reason with you like she usually did.

Tenzin, look, I have been trying to keep everything at bay, it's just that it awoke inside me so suddenly, I couldn't react properly, I'm a non bender, i shouldn't be able to do this, this bending air isn't akin to yours, but trust me, everything is under control, I can manage it, I promise, it won't affect kids.

Pema was trying to steady herself, even if the situation wasn't usual. It was clear that you had to help her out and teach her the air bending in order for her inner core to get stable.

How will you do it? Only knowledge is necessary.
