My toddler (3.5yr) has started coming up to me when I'm practicing and strumming the bass. He's really into it and I want to motivate him to keep enjoying "playing" the bass. I know some of the best bassists started when they were around this age. Anyone have any experience teaching very young kids? Is a kid sized bass recommended or should I just let him mess around with a full size one? Is it mainly just about right hand strumming and not much notes at this age? Just looking for any tips or advice anyone has around this. Thanks!
