Is it possible to have a career as a secular artist and still sing children's music?

Hear me out lol. I love RnB music. But I like the 'old' type. . .the ones with flowery lyrics and not really modern RnB. Though John legend still sings like that but the style I like is more of a Boys II Men sound.

On the other hand (don't judge me😂) I enjoy listening to music from when I was young. And I enjoy playing with kids. I'd also like to write an album of kids music, and subtly add positive moral themes into the music.

(These are just wild dreams BTW, life is pushing me towards becoming a civil engineer with a 9 to 5 job but I'm just asking 'what if?')
