As a relatively new father (my daughter is around 2.5 years old), you have plenty of time. They'll be a loving little lump for a while.
What she has loved so far:
- Bluey (a beautiful show about parenting in disguise as a kids show)
- Mister Roger's Neighborhood (all episodes available on archive.org, but they have to be reorganized/renamed at least for Kodi tagging)
- The Mhppets Show (and anything else muppets)
- (Modern) Mickey Mouse Clubhouse (cg show, and Clubhouse+, the short renewal)
- Dragon Prince
- Sesame Street
- Moana (2 to a lesser extent)
- Finding Nemo/Dory
- Lion King
- Little Mermaid
- Bedknobs and Broomsticks
- Mary Poppins
- Aladin
- Frozen (and all the spinoff stuff)
- Mickey Donald and Goofy: Three Musketeers (this is her current obsession, probably watched it 10 times in the last week)
I'll come back and edit this with my own shows later.
