FYI I have not read some novels for this lol so silly headcanons.
When Sakura gave birth at Orochimaru's lab, tsunade went to that place just to see If sakura was doing well. Tsunade still has powers and requested more ninjas to guard since that's quite literally a legendary child.
Naruto actually lowkey laughs when Boruto would deface his own face, reminding him of his childhood. He's finally realized how troublesome he was as a child.
Pretty sure this is canon in the anime, but Karin feels paternal towards sarada. She took care sarada along side sakura after all and had probably witnessed her first words and steps.
Sasuke's dad, fugaku would have seen the error of his ways like hinata's dad. He would be a doting grandfather if he was alive. Another thing is if he was alive, he'd be the most supportive of sarada being hokage. (since canonically, fugaku was apparently the other candidate other than minato if I'm correct). He'd also be surprised sarada unlocks/upgrades her sharigan through love.
Temari do actually wishes shikadai learns more of her wind technique, in anime shikadai is capable of using temari's wind style fan. Also in OG Naruto, shikamaru wanted to be a girl dad lol so he mostly have been expecting a girl and bought girl clothes before shikadai was born.
+ to this, Gaara canonically send tons of gifts to shikadai. Before Gaara adopted shinki, Gaara would lowk beg temari to bring his nephew to the sand village. Kankuro along side made a puppet for baby shikadai.

Damn wow, is boruto actually worth watching ??i watched Naruto a while ago, and when Boruto first came out I was planning to watch it too. But it got so much hate and backlash that I completely lost interest. Everywhere I looked people were saying it was terrible and a waste of time
