Cecil, that thing about letting them choose is totally 100% true. My daughter is that way with music. If it were up to me, I'd have her all over the guitar like her daddy, but she's in love with this $200 cheapy drumset I bought. I just let her go, and now she's a damn fine drummer at the age of 5!
Speaking of daughters, I need to teach mine to ride so we can have a daughter vs. daughter shootout. Your kid might whoop my kid's ass though. She looks like she knows what she's doing.
