Poly & Parents
This is a question for any polys out there who are also parents, mothers and fathers.
You and your partner have SOs. Your children are comfortable with the SOs in one or both of your absence. Is this A) Relieving (My children are safe when I'm gone, are comfortable with this other person caring for them) or B) Threatening (Oh, God, my children are replacing me with a new mother/father). Assuming the SO in question has made no indication of wanting to replace, but is merely trying to be accommodating to your needs.
Please only respond if you are actually a parent. Do not have to have experienced this personally. And please be honest.
