Hi A.,
I started lessons when I was 5 on the piano. It has had such a impact on who I am today, I've been playing for 20 years. Like others have said, its easier to go from piano to other instruments. Usually private lessons will start off about 30 min per lesson, 45 if doable would be better if child can handle that. Tuition for the month would be between $130-200. I actually teach you could message me for more information if your interested. I could also recommend the amazing teacher who taught me...she lives in Carrollton near Rosemeade and Furneaux if you are familiar with that.
Hope this helps! :)
