Looking for a Kirk/McCoy kid fic

[dondefluir.livejournal.com]

Hello everyone!

 The Enterprise goes to a certain planet for diplomatic purposes or something like that. What did interest me was that Kirk and McCoy were later presented with a child, created from both their genes, as a gift from the planet. McCoy had to take on the responsibility of raising her/him (I don't remember), because Jim was kinda reluctant about letting himself be a parent. 

I hope you can help me, because I've looked everywhere but I just cannot find it!
Thanks!
