One possible theme could be family. Since French culture often emphasizes family values, the story might revolve around the little girl's relationship with her family members, like her parents, siblings or grandparents.
Another theme could be the beauty of France itself. The story could describe the charming French landscapes, from the vineyards to the cobblestone streets. This would show how the environment shapes the little girl's experiences and her sense of identity. Also, the theme of growing up and self - discovery might be present. As the little girl experiences different things in her life, she learns more about herself and what she wants to be in the future.

As I don't know the exact story, it's hard to say the moral. But if it's a story about a girl facing difficulties and persevering, the moral could be about the importance of resilience.
The themes could include adaptation. Since being turned into a little girl is a huge change, the character has to adapt to a new physical form, new social expectations, and new ways of thinking. Also, the theme of discovery could be present. Discovering the world anew as a little girl, things that were overlooked before might become important now. There could also be a theme of loss, losing the status and abilities that came with being an adult.
Another theme could be family. Maybe the story shows how her family influenced her or how she supported her family. For example, if she was from a single - parent family and she had to take on more responsibilities at a young age, family would be a central theme. The story could also revolve around the theme of friendship. She might have had a special friend who helped her through tough times or they went on adventures together.
Another theme might be protection. The mommy protects her little girl from harm, whether it's physical danger or emotional distress. For example, she might shield her from mean kids at school or console her when she's feeling sad. This theme emphasizes the role of the mother as a protector in the little girl's life.
Another theme could be observation or voyeurism. The fact that someone is observing the girl in the window implies that there is a sense of watching and being watched. It could also be about innocence, as a little girl often represents purity and naivete.
One possible theme could be love. The father - daughter relationship is often full of love. Another could be growth, as the girl Ems might grow and develop with her father's influence.
One possible theme could be resilience. The little girl might face hardships but still manages to bounce back.
