There is almost no difference vocally in children in how they sound be it male or female.

Oliver's voice can stand in for either gender, ditto so can Yuki's. Vocaloids such as Len or Flower wouldn't be able to be gotten away with, if there was such a great difference. I'd rather have a new voicetype since Oliver already covers the child voice for the moment. Unless the child is much younger there will be so little difference. :-/
