How would a character in a 'woke up as a girl' story react initially?

Since we don't really know the details of the 'woke up baby girl story', the main character is most likely the baby girl herself.

Some people might immediately side with the girl, especially if they find out the boy was in the wrong first. For example, if he was the one who started the trouble by being aggressive.

On the other hand, if he has moved on completely, he could be polite but distant. He would listen to what she has to say but make it clear that his life has moved in a different direction and he is no longer interested in rekindling anything.

At the start, the boy could be in a state of denial. He might think it's all just a really bad dream. He'll go about his normal routine, like getting dressed in his boy clothes, but then realize that things don't fit the same way. He'll start to notice the physical differences more and more, and as reality sinks in, he could become angry. Angry at whoever or whatever did this to him without his consent, and then he'll start to think about how to deal with this new situation.

There would likely be shock and confusion. People around her would be at a loss for how to handle such a situation. Her family and friends might initially be in denial, thinking it's some sort of prank or a medical misdiagnosis.

A possible 'woke up a girl story' could be that one morning, I woke up a girl who had fallen asleep in the park. She was so exhausted from a long hike the day before. I gently tapped her shoulder and when she opened her eyes, she was initially disoriented but then realized where she was. She thanked me for waking her up as she was worried about missing an important appointment.

One possible plot could be a boy who wakes up in a girl's body and has to navigate the new social and physical experiences. For example, he might struggle with dressing in a more feminine way at first. He could also face different expectations from family and friends. Maybe he has to deal with things like wearing makeup or having different hairstyles, all while trying to figure out how to change back to his original body.

I'm not sure specifically what the 'woke up baby girl story' is. It could be a very personal story about a girl waking up in the morning, perhaps experiencing something special or ordinary like seeing a beautiful sunrise from her window, or it could be about waking up to a surprise like a puppy in her room.

She might be initially shocked and confused. She would probably look at her new body in disbelief, trying to figure out what had happened.

At first, Harry might be extremely confused. He trusts Sirius to a certain extent, but being kidnapped is still a shock. He would probably ask Sirius a lot of questions like 'Why are you doing this?' and 'Where are we going?'
