I'm surprised by often I'm hearing this , not just on MN, but in various parenting groups. Parent makes a decision that is likely to have a detrimental impact on their child(ren): conceiving a child by an anonymous donor, or moving a biracial child to a predominantly white area where they're the odd one out, or moving their boyfriend in even though the kids are unhappy about it. When people ask about the impact on the children, the parent brushes it off with "I'll get therapy for them when they're older".
I really don't think this is great parenting. If anything, it demonstrates how far therapy culture has spun out of control. A painful or traumatic situation isn't going to be magicked away by therapy. It's better not to make your child suffer in the first place.
Also, I think there's an unspoken undercurrent of "the therapist will help my child see I did the right thing for them", because realistically most parents aren't going to be gung-ho about therapy that may turn their child against them. But the truth is that, for many people, therapy actually validates the anger they already felt towards family members.
