Oh, geez, those Daisy Rockers are like 3/5ths size...I have a fourteen year old daughter who plays guitar and we've been buying her full size instead of fractional size guitars for while. Friend of mine recommended a smaller axe and we went with it and it was just a tragically poor instrument so we just started buying "regular" guitars for her...there may be some fractionally sized guitars or basses out there but you would probably pay as much for a quality one as you would for a full size instrument. Taylor guitars would be an example of this; they make smaller guitars but they cost like the full size. Have the child try out a full size and see how it feels....and I have seen electric basses made with short, standard and extra-long necks...my brother had a Gibson SG Bass with the XL neck...very tasty instrument...he should have hung on to it.
