Learning shows that are a “next step” from Rachel/Caitie/Blippi

My son is 4 and still likes Miss Rachel and Caties Classroom but I don’t feel like he actually learns anything new even with the preschool episodes.

He doesn’t really like cartoons and seems more into a “real person” and learning …is there a “next step” from Miss Rachel that is a similar format? And not Blippi 🙃

He doesn’t have very specific interests which makes it hard! Appreciate any suggestions.
