I don't think therapists are any better at raising children than anyone else necessarily. I have friends whose parent/s were therapists - and they are no better at life than anyone else. I have friends who are therapists who have children. They have addiction problems, school problems, relationship problems, life problems just like everyone else. The first one I see has said one of her children rarely talks to her and that she has issues with her daughter-in-law. I have read articles by the children of therapists and they ***** and moan and see their own therapist to deal with how they were raised just like others. Some just report unusual childhood interactions.
