Hi there I have a 3 year old son. At my place, at his fingertips to play with I have a synthesizer, a plastic Sesame Street drum kit, a bass, and a full size acoustic guitar. Wondering about your suggestions to, while I let him explore and play with the instruments as he wishes, what steps to educate him musically off and on instrument. Of course we often listen to music at home and in the car, kid and non kid music. Also wondering if I should spend the money on a baby guitar. I do have an old classical adult size but it always runs the risk of getting destroyed. His favorite thing so far is to bang on the plastic drums, and messing with the keys. Guitar seems harder, he may try to pluck the strings. Thank you!
