My dd loves Finding Nemo, too. (The first few minutes are scary, though.)
Â
Dd is almost 4 and also very sensitive to movies; she is afraid of scary/ominous music, scary/ominous lighting, people yelling/arguing, etc. I honestly don't think she could handle some of the scenes in Mary Poppins, such as the scene at the bank.
Â
We have Netflix, so can stream all kinds of material. She loves to watch episodes of Dora the Explorer.
Â
A movie we found that she adores is The Ballet Shoes. She also liked Fly Away Home, but there is a kind of sinister guy in there trying to thwart their efforts.
