Insidious

1. What does "insidious" mean in the following context? Does it mean "hidden"?

2. Does "modelling the infant on the toy" mean "making toys similar to infants i.e. representing infants in toys"?

Kelley is interested in how these codes of clean and proper bodies get projected onto the handmade toys that he used in this period in his work.

"To parents, the doll represents a perfect picture of the child – it’s clean, it’s cuddly, it’s sexless, but as soon as the object is worn at all, it’s dysfunctional. It begins to take on characteristics of the child itself – it smells like the child and becomes torn and dirty like real things do. It then becomes a frightening object because it starts to represent the human in a real way and that’s when it’s taken from the child and thrown away".

For Kelley what is even more insidious in terms of modelling the infant on the toy is that toys have no genitalia, which are displaced by other abnormal bodily features such as enlarged heads.
