When Molly was seven months pregnant with Fred and George, Arthur started to really get on Molly's nerves because he would always teasingly say that being pregnant with twins wasn't much different then being pregnant with a single baby. So one day, when she couldn't handle it anymore, she gave him a potion that allowed men to experience pregnancy instead of the pain potion he had asked Molly to get him.
When Arthur's stomach increasingly got bigger and his ankles started to swell, he started questioning Molly about the potion she gave him. Immediately she smiled and sweetly said, "Congratulations, Daddy," and patted his very round stomach. It took him a few seconds to realize what she had meant, but he quickly caught on.
Arthur soon started to realize that maybe being pregnant with twins, or being pregnant at all for that matter, wasn't as easy as he had been saying it was. He found he was always going to the bathroom, he couldn't walk very well and his moods were all over the map. He had taken for granted how much women put up with when they're pregnant and that didn't include taking care of three other kids.
Once the kids had gone down for the night, Molly sat down on the couch where Arthur was sitting. "Isn't as easy as you were thinking, hm?" she asked as she leaned into the couch and rested her hands on her seven month pregnant belly.
"I'm so sorry, love," Arthur replied as he looked over at his wife apologetically. "I never realized how much you put up with when you're pregnant," he said. Right as he said that, he felt a kick against his rib cage. He let out a soft gasp as he hands flew to his stomach. He started tearing up and Molly's quizzical look went to one of understanding.
"Did you feel a kick?" she asked. Arthur nodded his head as he wiped away a tear that had rolled down his cheek. "Just wait until you feel one while you're sleeping," she said as she leaned over and kissed him. She laughed when Arthur realized that this potion Molly had given him wasn't going to wear off anytime soon.
"When did you become like your brothers?" Arthur asked as both Molly and himself tried as best they could to get off the couch. "I've always had it in me, love," Molly replied. "It just rarely ever comes out."
