Eliza was now crawling around everywhere and Kurt and Blaine had got to the point where changing her on the change table was too dangerous because she could roll herself off it. Kurt was changing the girl on his bed, and four year old Aiden was distracting Eliza liked Kurt had asked him too so she wouldn’t roll around as much. The small girl was looking at her big brother with her big blue-green eyes like Kurt’s, laughing and clapping her hands at the toy he was dangling in front of her which she grabbed and threw in the direction of Kurt.

“Daddy,” Aiden noticed the naked half of his sister’s body going to pick up the toy that had been thrown. “Why doesn’t Eliza have a wiener?”

Aiden was at the age where he asked a lot of questions, and Kurt was just hoping this wasn’t going in the direction he thought it would.

“Because Eliza is a girl.” Kurt answered, concentrating on putting a new diaper on the girl.

“Girls don’t have wieners?” Aiden had the same confused face that Blaine always did.

“No, only boys do.” Kurt responded.

“So you have a wiener?” Aiden asked as Kurt nodded. “And Papa has a wiener?”

“Yes.” Kurt nodded.

“But Aunt Rachel and Natalie don’t?” Aiden asked.

“No, they are girls, so they have vaginas” Kurt responded.

“Oh,” Aiden paused. “Thanks Daddy.”

Kurt breathed a sigh of relief as he lifted the girl up and carried her downstairs as Aiden walked behind them. It wasn’t till after Eliza had been put to bed that night and they were reading Aiden a bedtime story that he brought the topic up again.

“Daddy,” Aiden looked at the taller man. “Why do boys have wieners and girls have va-va-”

“Vaginas?” Kurt said as the boy nodded.

Kurt looked at Blaine before the shorter man responded.

“Because when girls become older, they can have babies in their tummies.” Blaine responded.

“But daddy had Me and Eliza in his tummy, right?” Aiden asked. “And Daddy has a wiener.”

“Oh god.” Kurt mumbled as Blaine tried to hold back laughter.

“Well Daddy us very special because not a lot of daddies can have babies in their tummies,” Blaine responded as the boy nodded. “Like you and me Aiden. We can’t have babies in our tummies.”

“Oh,” Aiden paused. “But daddy can because he is special and Eliza can because she is a girl?”

“Yes,” Kurt now responded. “But Eliza only can when she is older.”

“Much, much older.” Blaine added, now thinking about the fact that his baby girl was going to be an adult one day.

“That makes sense.” The boy smiled.

“Have we answered all your questions?” Kurt asked.

“Yep,” The boy smiled closing his eyes. “Night Daddy, Night Papa. I love you.”

“Love you too.” Kurt and Blaine said in unison as they left the bedroom and Kurt sighed in relief.

“You were great Blaine,” Kurt shut his eyes as the shorter man came over to him. “How did we have such a curious child?”

“I am sure that every four year old is the same,” Blaine laughed. “You were pretty great yourself, Kurt.”
