A lot of kids who appear nonverbal at first end up being gestalt language processors! So shows with lots of songs & like a structured routine of how the show starts even if the topic is different every episode can be super helpful (:
Where abouts are you from?
Super simple songs, my daughter still don’t speak but she will copy the songs. Miss Rachel she’s always watched and never copied but the last few months she’s tried to.

I like Vooks. It is like storybooks come to live, it is not too hyperstimulating like Cocomelon. And Super Simple songs
Daniel tigers neighborhood is a good one! Bubble guppies was one that my youngest brother watched a lot when he was working on his speech! (Lots of repetitive words used, sing songs about stuff like every episode & they touch on counting n stuff) (definitely a day time show tho)
