KKG is inside the DNA of a shinobi which is allowing him to mix two natures, THIS can be given to the children, BUT in narutos case, he cant give it to them since his DNA is sill the same... the kids can gain the nature by having the bijuu helping them and lending them his/her chakra ^_^"

- who told you naruto can't use them bijuu giving it to him?, go read databook pages on roshi and six paths sage mode the answers lie there and stop using your own bias ^_^ knowledge

exactly the bijuu gave him the change in chakra nature as in they literally said here naruto we are going to change your chakra to this nature. in doing so naruto gained the natures they gave him and it is permanent
