Author's Note: I have edited the children's ages based on a review I received.
Molly Weasley knew how to handle chaos. When you had seven children, you had to know how to handle chaos, especially when your husband was away at work for most of the day and you were the only adult around to keep an eye on all those children.
Bill no longer lived at the Barrow because he had gotten his own place since starting his job as a Curse Breaker; but he was currently on vacation from work, so he had decided to spend some time at his childhood home with his family. Charlie and Percy were Hogwarts age. Fred and George were about to start their first year at Hogwarts. Ron and Ginny still had a few years to go before they would be old enough to go to Hogwarts.
It was currently the summer holiday, though, so Molly had all her children at home.
One morning after breakfast, Bill and Charlie went outside to see what types of animals they could find and study. Bill didn't like animals or the outdoors nearly as much as Charlie did; but the two oldest Weasley children had always been close, and they both did activities that the other enjoyed doing more.
Percy, Fred, George, Ron, and Ginny were all in the Burrow somewhere. Percy had muttered something at breakfast about doing some reading in the room that he shared with Fred and George. Seeing the mischievous grins on the twins' faces, Molly had quickly warned them to leave their brother alone.
"Yes, Mum," both Fred and George had said, even though Molly seriously doubted that they would be able to stay out of trouble for the entire day.
Ron and Ginny had said that they were going to play some games together in Ron's room.
Despite the fact that there were five children inside the house, it was relatively peaceful for about an hour. Then, chaos happened in the forms of Fred and George Weasley.
Molly wasn't able to make out from Percy's tirade what exactly had happened, but she was able to make out enough to know that Fred and George had played some sort of prank on him.
Molly first had to restrain Percy from lunging himself at his brothers, much to the twins' amusement.
After calming Percy down, Molly yelled at Fred and George and told them to go to their room until it was time for lunch.
"Let me at least get the book that I was reading before they go in there," Percy grumbled.
For a while, there was once again silence. Then, Molly began to hear a lot of bangs and other sounds coming from Percy's, Fred's, and George's room.
"I can't concentrate," Percy snarled as he walked past her, a book in hand. "I'm going to go read outside."
"Lunch will be ready in about an hour," Molly told him.
"All right," he returned. "I won't go far."
Molly then went upstairs to talk to her twin sons.
"But you only told us that we had to go to our rooms, Mum," Fred said. "You didn't say anything about us having to be quiet as well."
Molly was torn between annoyance and amusement.
"All right," she said. "You can keep doing whatever it is that you're doing. But if Ron and Ginny start complaining, then you're both are going to have to lower the noise level."
"Yes, Mum," both boys said.
Molly then went to check on Ron and Ginny. They were playing Wizard's Chess.
"Are you two doing okay?" Molly asked.
"Yeah, Mum," Ron grinned. "I've already beat Ginny twice."
"You don't have to rub it in my face," Ginny grumbled.
"Don't be mad because I'm better than you at something," Ron snarled at his sister. "You can't always be Miss Perfect."
"Ronald Weasley, apologize to your sister," Molly snapped. "You know better than to talk to her like that."
"Yes, Mum," Ron said in a subdued voice. "I'm sorry, Ginny. I just sometimes get a little too much into Wizard's Chess. I love that I'm good at it."
"That's all right, Ron," Ginny replied. "I can be the same way when it comes to something I'm good at. Want to play a game of Exploding Snap?"
Ron grinned. With Exploding Snap, you never knew when the cards were going to explode, so the game was always exciting.
"Let me get my cards," Ron said excitingly.
Molly smiled fondly at her two youngest children before leaving the room.
When it was time for lunch, Molly was able to find Percy relatively easily. He had not gone far, just like he had said he wouldn't.
It took a little longer, though, for Molly to find Bill and Charlie.
"Sorry, Mum," Charlie apologized when they finally heard her calling for them. "We lost track of time."
"That's all right," Molly smiled. She then wrinkled her nose. "But you two do need to wash up real quick before you come to eat. Do I want to you what you two have been up to all morning?"
"Probably not," Bill grinned.
Lunch was very pleasant, as all the children were too busy with stuffing food into their mouths to talk much.
As soon as they were finished with eating, all the children stood up to leave.
"Now, now, you all know better than that," Molly spoke. "Help me clean the dishes. Then, you all can go do whatever you want."
"Yes, Mum," all the children said.
As soon as the last dish was cleaned and dried, all the Weasleys took off in different directions.
Once again, it was peaceful for a while. Then, Molly heard the sound of Ron yelling at someone. From the sounds of it, he was yelling at Fred and George.
Molly quickly make her way up the stairs, only to be greeted by the sight of the twins running down the stairs towards her. They were closely followed by a small but ferocious looking Ginny.
"You two bullies, pick on someone else for a change," Ginny told them.
"What did you two do to Ron?" Molly asked them.
"Nothing, Mum, really," George insisted. "You know how sensitive Ron can be."
"Do you two want to spend the rest of the afternoon in your room and unable to make any noise?" Molly asked them in a warning tone of voice.
"No, Mum," the twins said quickly. "We'll be good. We promise."
"Why don't we go outside for a while, George?" Fred then suggested.
"That sounds like a wonderful idea, Fred," George responded. "We could play a game of Quidditch."
"With just the two of you?" Ron pressed. "I want to play as well."
"So do I," Ginny spoke up.
"Sorry, Gin," George grinned good-naturally, "but we don't want to risk you getting hurt. We don't care if Ron gets hurt."
"Hey," Ron said.
"Just kidding," George laughed. "You know we love you, Ron. You're our little brother. Let's go see if we can get either Bill or Charlie to play with us. That way, we will be even."
"You could be even if I played," Ginny muttered.
Fred, George, and Ron, however, paid Ginny no attention. They practically ran down the stairs, talking excitingly.
"Sometimes I really hate being the only girl," Ginny pouted.
"I know, sweetie," Molly said soothingly, "but one day your brothers will fully appreciate you and what you're capable of. Would you like to help me with some sewing? I really do need to find out what Bill and Charlie are doing outside."
"All right," Ginny mumbled. It was clear, though, that she was still a little disappointed at being rejected by her brothers.
As they were sewing, though, Molly told Ginny stories of some of the embarrassing things that her brothers had done both before she had been born and before she had been old enough to remember. It didn't take long for Ginny to start laughing in delight.
"Just wait until Fred and George tease me again," Ginny grinned mischievously. "That will give me a reason to remind them of their potty training mishap."
"They had a lot of those," Molly laughed with obvious fondness.
"How was your day?" Arthur asked Molly after he had kissed her on her lips.
"The same as usual," Molly smiled. "What about yours?"
"It was very interesting," Arthur grinned, "but I'll wait until the rest of the children are here before I share all the details."
He then picked up Ginny and kissed her on her cheek. Ginny grinned happily at him.
"The children do love your work stories," Molly said fondly to her husband. "Let me go call them."
"You really are amazing, Molly," Arthur remarked. "I know that it can't be easy to manage seven children, but you make it look easy."
"It's nothing really," Molly blushed, exchanging a smile with her husband.
She then made her way past Arthur and Ginny so that she could go outside to find the rest of their children.
As Molly was walking out the room, she could hear Arthur asking Ginny about her day.
Molly smiled as she listened to Ginny's excited chatter. Just hearing how happy her children were was always enough to make up for how rowdy and noisy they could sometimes be.
