Be prepared for the possibility that your children, particularly preteens or teenagers, will reject your polyamory outright. It may take them years to understand and accept. In fact, polyamory may become part of the focus of their teenage rebellion. They may hurl toxic judgments at you, as happens to lots of parents with teenagers; you've just given them a special target. The fact that it's to be expected—and ultimately not about you—doesn't mean it won't hurt. Have faith that by the time they are adults, they are likely to come around.
