I had a quick look but not with my kid yet.

The story I chose didn't include the interests I entered.

I like length and pace of each section.

The story had the same generic style that a simple prompt such as tell me a children's story with a few themes and a problem/goal. Perhaps try to give the stories a bit more character.

Consider removing A/B and use the option directly as the text for the button. Keep it simple.

Nice work.
