Fans love Shipping. Fans love cute kids. And sometimes the the most popular couple in the show will end up being composed of two of the cute kids. This results in the occasionally squicky practice of Shipping two characters who are barely old enough to be in a relationship (but in fairness this isn't as squicky as pairing them off with adults). A Toy Ship does not automatically qualify as Squick since usually people only support innocent childhood crushes between the two; most writers and fanfic authors let these characters age a bit before making moves. Most.
