This story shows Sirius and Regulus Black's childhood encounters with the Rosier family, including Evan Rosier and Evan's brothers Tristan and Damien (my OCs). For the first few chapters, Regulus and Evan will both be very young so won't be interacting much.

Growing Up Pureblood: A Tale Of The Black And Rosier Family

Chapter One: Age Two

Tristan Rosier had been touching Regulus all morning and two-year-old Sirius hated it. He didn't want Rosier there at all, but his Mother wanted the two of them to play together while Mrs Rosier was in Hospital. Mrs Rosier was going to have a baby and both she and Mrs Black thought it would be wonderful for the four children to grow up together.

"Stop it," whined Sirius. "Reg not like it."

"He does. Look…" argued Tristan. The almost two-year old continued to circle his tiny finger around Regulus's even tinier palm. Baby Regulus remained calm and content in his cot.

"No. He not smiling," said Sirius. "He not like you."

"Too small," said Tristan, not really knowing how to construct sentences properly. "Regulus baby. Baby not smiling."

"Does smile," argued Sirius. Baby Regulus had indeed smiled for Sirius, but only when Sirius had shown the baby his favourite toy.

Tristan Rosier decided to tickle Regulus and was delighted when the baby actually smiled. Sirius then became jealous and pushed Rosier away from the baby. Regulus started to cry.

A few months later

…..

Evan Rosier was three months old now and Regulus was seven months old. The two of them were being held by their respective mothers while the older children celebrated Tristan's second Birthday. A heavily pregnant Mrs Mulciber also sat by them, discussing frivolities with Mrs Black and Mrs Rosier while her toddler joined in Pass the Parcel.

"Everyone sit down in a circle," instructed Mr Rosier. Two-year-old Sirius, Tristan, Mulciber and Wilkes, four-year-old Lucius Malfoy and even one-year-old Crabbe did as instructed, but the eldest Rosier child didn't want to. Four-year-old Damien Rosier was fed up with both of his brothers getting all the attention and didn't want to join in.

"Pass the Parcel is for babies," he stated, not sitting down with the others.

"Sit down, Damien," said his father.

"No!"

"If you don't sit down, you won't be getting any Birthday cake," said Mr Rosier.

"Fine! I won't have any Birthday cake then!" the four-year-old stropped. He stomped out of the circle the younger children were sitting in, making sure to roughly kick his little brother on the way out. Mr Rosier let him go, turning to comfort the now crying two-year-old. It wouldn't have been so bad if little Henrik Mulciber hadn't also started crying in empathy.

"Want to play parcel game," contributed Sirius. "Now!"

Mrs Rosier, who'd given Evan to one of her friends to hold, ran over with Quidditch Ted and Doggy, two of her son's favourite toys. At the arrival of Doggy, a fluffy, yellow toy dog the little Rosier boy quietened. Mulciber seemed quite entertained by the teddy on a broomstick.

"Please could we get on with the game, Sir," said Malfoy. "Some of us have been waiting patiently."

Mr Rosier sighed. Even at four, Lucius Malfoy was a well-spoken but obnoxious and self-important child. He'd only been invited to placate his oldest, who'd now stormed off.

"Okay, when the music starts, you will pass the parcel between yourselves. When the music stops, the person holding the parcel will open one layer of wrapping. Any questions?" Mr Rosier said. The toddlers stared blankly at him.

The small children passed the parcel along until it got to Mulciber, who was so interested in the teddy that he hadn't noticed it. Sirius, who'd just passed it to him, picked it back up again and threw it to the next person. Then the game continued. Behind each layer was a small present but on the final round it landed on Mulciber. He unwrapped it to find yet another Quidditch teddy.

Weeks later

…..

The next time the Blacks and Rosiers met up was for a tea party at with Druella Black. This meant that Sirius's cousins would probably be there too.

However, when Sirius arrived with his Mother and baby brother, only Bellatrix was available to play with him while his Mother had tea. She was sitting in an arm chair with Tristan Rosier on one of the arms and a book in her lap. Sirius climbed up to sit on the other side of the older girl.

"Once upon a time there was a great city of witches and wizards," Bellatrix began, opening it to a page with an illustration of a walled city. "It had high walls and spells to keep the muggles out and Quidditch could be played throughout the streets."

"Brooms!" Tristan pointed at a wizard on broom that was swooping across the sky.

"Yes, that's a broom," Bellatrix said in an exasperated tone. She turned to a page showing a family of wizards. "Antioch lived with his Father, Mother and two little brothers. He was excited. Today his father was taking him Muggle baiting."

"What's that?" asked Sirius.

"Listen and you'll see," smiled Bellatrix, turning over to a page that showed the man and boy riding out of the city gates on horseback. There were no words on this page - just the sound of hooves as the horses rode across the page and onto the next, forested page.

"They rode until they came across a farm next to a village. This was where the muggles lived."

"Dirty muggle," said Tristan. The muggle man in the illustration was working in the fields and was covered in mud.

"Antioch's father flicked his wand and the plough started to move on its own," read Bellatrix. The illustrations changed to match her words. "He laughed as the man looked around in confusion." She turned the page. "Suddenly, all the tools were moving. The seeds were planting themselves the crops were growing higher and higher. Then they harvested themselves, and the plough moved until it was back where it had started."

"Antioch and his father had had a good laugh at the muggle, and given him a whole year's worth of crops too. Everyone was happy, even if the muggle was a bit confused. The end."

Sirius looked at Bellatrix puzzled. "Why were they nice?" he asked.

"This was before the muggles started hunting witches and wizards. The wizards looked down on them and pitied them, so sometimes they helped, but only if it was fun," said Bellatrix.

"Want a different story," Sirius said.

"Do you want another Antioch story, or something a bit more interesting?" she asked.

"More interesting," said Sirius. At the same time, Tristan requested the opposite, wanting more adventures of Antioch Peverell, which were completely historically inaccurate anyway.

"Ok, how about Cadmus and the Veil of Death," said Bellatrix. Neither of the two boys had ever heard this story before, and neither of them enjoyed it. In fact, it gave both of them nightmares for days.
