-Alright so this isn't exactly an x-men evolution fic, but it was the only x-men option with pietro and wanda as characters:P
Anyway, this story will be a mix of comics and x-men evolution.
For this story, Erik was with Wanda while she was pregnant and when the children were born.
This story will mainly be about Erik raising his children so I will include spankings in some chapters.
The title of this story is from the song by Pink, because I feel it fits very well with Pietro and Wanda:)-

Erik lived with his pregnant wife Magda on Wundagore mountain in Romania with Bova who would help assisted Magda throughout the pregnancy and would assist with the birth.
They lived in a beautiful little house surrounded by green grass, fruit trees, and animals. It was very beautiful place with a stream nearby. They lived there on the land with no neighbors to bother them for miles.
Erik sat on the couch by the fireplace,with Magda sitting on his lap. He placed his hand on her stomach just in time to feel the gentle kick of the baby followed by some harder faster kicks. To their knowledge, there was only one baby inside. They had set up the baby furniture in the corner of their room and decorated it with flowers and baby animals and all sorts of things used to soothe babies.
Both Madga and Erik were excited for the baby to arrive, it was due any day now and Erik seemed to be the more impatient one, wanting to see the baby born already and wanting to know if he had a precious little girl or a lovely little boy. Magda only smiled at her husband, gave him a kiss, and told him to be patient and wait. Neither of them had had a preference to the baby's gender. All they wanted was a little one to look after and raise together in their beautiful little home.
Magda had spent most of her pregnancy making clothes for the baby, she hadn't made the clothes with any gender in mind, she only made it cute to her liking, which made all the baby's clothing more on the feminine side. When Erik would protest as to why she made female clothes she would argue that it was only baby clothes and it had to be cute. If that meant adding little ruffles and ribbons, then that's what it meant.
After dinner, Erik took his precious Magda to a bath to help her relax then took her to the bedroom and helped her into her nightgown before laying her in bed.
"You are beautiful, my dear." He whispered as he ran his fingers through her black silky curls. He lay with her, admiring her beautiful pale skin and red felt immensely lucky to have such a woman with him and carrying their child. He wrapped his arms around her waist and slept with her through the night, but he made sure to always be attentive in case she needed anything.
The next morning Erik had gone into town to pick up some fresh goat cheese and liver to satisfy a craving Magda had come up with.
Erik had always tried to prepare himself for the arrival of his child, wanting to be there to help support Magda through the pain.
As his luck would have it, Magda's water broke while Erik was away, but Bova was still home to help.
Erik came back some hours later with the fresh goat cheese and livers Magda had wanted. He went into his home and set the foods on the kitchen counter when he heard Madga scream in pain.
"Magda!"Erik grabbed a knife in case he'd be needing it and ran up the stairs. He shoved the door open ready to surprise whoever had broken into his house and hurt his wife. He dropped the knife when he saw that Magda was in labor. He ran to her side and held her hand. He looked to Bova wondering how long she had been in labor for and if there had been any complications.
He had thought he would able to do this just fine, but seeing Magda in so much pain killed him.
Minutes later, the sound of crying could be heard in the room. And two minutes later, it seemed the crying had doubled...
Erik couldn't believe it when he saw Bova with two babies.
Magda smiled, "Erik, we have twins..." She said her voice happy, but weak.
Erik didn't know what to say, he was so happy.
Bova put both of the crying children in Madga's arms.
The black haired baby was a girl, she cried much like a normal baby, hungry and cold and new to the world. The silver haired baby was a boy, his cries were much louder and exagerrated than the girl's cries.
Erik smiled and took the silver haired child from Madga so that she could try calming the girl while he comforted the little boy.
Once in his arms, the little boy calmed down. The little girl calmed now that her brother was no longer crying.
When both babies had settled, Erik gently put his little boy back with his mother so the twins could feed.
"What shall we name then,Erik?" Magda asked in a whisper, looking down at the babies.
"What do you wish to name them?" Erik smiled wanting to hear her suggestions.
"I think I want our little boy to be named...Lună" She told him, petting his soft white hair.
Erik laughed, "We are not naming our little boy Lună..."
"Why not? Fine, we will name him Zăpadă, our precious little fulg de zăpadă..."She smiled.
"No. We are not naming our boy Zăpadă."Erik scolded a bit, "He will have a proper name. We can name him Bazyli, or Jedrek, even Bialy if you'd like..."
"I like Bialy," She smiled, "Or what about Pietro? Bova suggested Pietro...He can be our little Pietro..."
Erik smiled, "I like Pietro," He looked down at the cute little boy who's only concern was to drink his mother's milk, "What about our little girl? What shall we name her? Alina, or Cereza, how about Rasine? She can be our little Rasine."
"No, Erik, I don't like any of those names." Magda protested, "What about Pisoi?"
"No,Madga. Our children will have proper names. They will not be named after things or animals."
"Oh Erik you're no fun...do you like Wendi then?"
"Wanda. Her name will be Wanda." Erik smiled.
"Very well, our little Wanda and Pietro."
