Well, in a toddler Naruto fanfic, you could have a plot where Naruto discovers a hidden power within himself at a very young age. For example, he might find out he can communicate with plants, which is something no one else in the village can do. This could lead to him making new friends among the plant - like creatures in the forest. Also, a story about toddler Naruto's first encounter with a simple ninja tool, like a shuriken, and how he plays with it in an innocent yet dangerous way would be interesting.
A toddler Naruto fanfic could center around Naruto's relationship with the other toddlers in the village. Maybe there's a toddler who is always getting into trouble, and Naruto tries to be a good influence on him. Or it could be about Naruto's first day at a toddler - only ninja training session, where he's excited but also a bit scared. He could make friends with a shy toddler during the training, and together they learn the basics of being a ninja, like how to hide and seek in a ninja - like way.
