Kurapika/Leorio. I think this was like, my sister's ship waaaay back in the day (like, we're talking over a decade ago Owo yes I'm old ||orz)
Who cried when they brought their child home for the first time: Both, just, all the tears.
Who would wake up in the middle of the night to check on the kid(s): Both
Who changes the kid(s) diapers: Both. This relationship really involves them both being an active part of their child‘s life. No matter how gross it might be.
Who makes the bottles: Both.
Who stays up late at night to rock the kid(s) to sleep and sing them lullabys: Kurapika, though Leo would sit in and listen too.
Who is guilty of spoiling the kid(s): Leorio mainly, but Kurapika isn’t all that innocent either. He’ll let the child get away with a few things.
Who would give the kid(s) cookies in the middle of the night: Mmm, maybe neither? They both know that it’s bad for them, but they may cave in occasionally.
Who always takes the kid(s) side: Depends, but I can see Leorio doing that more times than Kura.

Who goes to parent teacher conferences: Both
Who will be the first to suggest to have ‘the talk’ with the kid(s): Leorio
Who would choose their child(s) prom outfit: ahh, they would both go prom shopping with them and just so happy. They would want their child to have the prom outfit of their dreams.
Who would cry when the kid(s) go off to college: silent tears from both. Their baby is all grown up, just, tears.
