Ino would be very involved. Since she's Sakura's friend, she would be constantly checking on Sakura, giving her advice on pregnancy - related things like what to eat and what not to do. And she would also be helping with preparing things for the baby, like baby clothes and a nursery.
Naruto would probably be super excited and offer all kinds of help. He might bring over some of Hinata's home - cooked meals for Ino. Sakura would be very practical, offering her medical expertise and making sure Ino is having regular check - ups. Shikamaru would be more laid - back but still offer some sage advice about the responsibilities of parenthood.
The friends' reactions would vary. Ino would be thrilled for Sakura and would be eager to be the 'cool aunt'. Shikamaru might be a bit more laid - back but still offer his congratulations. Kiba might joke around about how the baby will grow up to be a great ninja. Overall, they would all come together to support Sakura and Sai during this new chapter of their lives.
Well, Sasuke might have a complex reaction. He and Sakura have a history, and while he would probably be happy for her in the end, there might be a tinge of something else. He could be worried about how the new baby would affect the balance of power in the ninja world. As for the rest of the Konoha villagers, they would generally be happy. They always welcome new life. The elders might be a bit more cautious, thinking about how the child of a powerful ninja like Shisui and a brilliant medic - ninja like Sakura could shape the future of the village. They would likely keep a close watch on the situation while also showing their support.
Their friends' reactions would be quite diverse. For instance, Ino, who was once Sakura's rival, would have a mixed reaction. On one hand, she would be happy for Sakura as they have grown to be friends over the years. On the other hand, she might feel a bit envious. Choji would be excited and would look forward to all the feasts at the wedding. As for Lee, he would be over - the - moon for Naruto and Sakura. He would probably give them some long - winded and passionate speeches about love and friendship.
Kakashi would be more reserved but still show his support. He might give Sasuke some advice on being a father based on his own experiences with his team. Shikamaru would be practical, thinking about how the baby will affect the village's future and offering some logical solutions to any potential problems that might come up.
Elena might be a bit shocked at first but then would be very supportive. She would offer her own experiences and advice, even if they are from a human perspective. Bonnie could be worried about the magical implications of a vampire pregnancy and offer to use her magic to keep an eye on the baby's development.
Their friends might be initially shocked. Some might be overjoyed and offer immediate support. For example, those who are close to them would probably start planning baby showers and getting gifts. However, there could be some friends who are worried about how this will change their group dynamic.
Sakura would probably be shocked at first, but then she'd be supportive. She might offer her medical skills to help with Tenten's pregnancy. Shikamaru would likely think it's a troublesome situation but would also offer his strategic advice on how to handle things. Kakashi would be his usual calm self and give them some wise words about responsibility and family.
Rory would be a mix of emotions. He'd be worried about Amy, but also feel a bit left out since she's having a baby with the Doctor. River might be more understanding, given her complex relationship with the Doctor. She could offer some advice based on her own experiences with time - travel and family. The other friends like Craig might be shocked but also try to support them in their own bumbling, human way.
If we consider Percy as one of their friends, he might be a bit protective. He could offer to help with any potential threats that might come their way because of the pregnancy. Annabeth, on the other hand, would probably be very organized in her support. She could help Reyna and Jason plan for the future, like making sure they have proper financial arrangements and a suitable living space for the baby. Some of their more light - hearted friends might make jokes about how their lives are going to change completely, but all in good fun.
