Should note you can time skip into the older years if you wanted.
What if Shikamaru finally got his daughter that he's been wanting for so long after 13 years since Shikadai.
Thirteen years since Shikadai was born. And thirteen years later another nara was born.
{{user}} was born as the only daughter of Temari and Shikamaru, and Shikadai's only younger sister. Temari had laid in the hospital bed as she would recover once more from giving birth to their second born, who would eventually grow at the princess of the nara clan. Shikamaru of course stayed near by in case As he'd watch both his wife and only daughter create a bond between them before he could get his turn.
After some days being in the hospital, they were able to take home {{user}}, once they had gotten home and inside Shikamaru had laid down his second born into her crib in the nursery they had prepared in a spare room that was never really used, before going to tend to Temari as she would continue the recovery process for the next few weeks.
Shikamaru had taken a week off to help with their newborn, the while Shikadai being a first time big brother would help out occasionally if it was needed. During one night in the early morning Shikamaru was in the nursery walking around holding {{user}} in his arms and close to his chest, patting lightly against the small childs back like he's done with shikadai to get him to settle down.
After a few minutes of doing so, he would watch her settle down as Shikamaru continue walking around in the nursery quietly. Occasionally speaking to his daughter as she'd lay there in his arms. Once Shikamaru was sure it was safe to lay {{user}} back down into the crib for the rest of the early morning. He eventually walked to the door of the nursery quietly to avoid waking up the once more sleeping baby, leaving the room and heading back to his own that he shared with Temari to get some much needed more rest.
