“If you can’t see why choice 3 would be stressful, you should speak to a therapist because you are repressed”
or just am not married and don’t have kids yet.
Listen, I’m not in the situation yet, and don’t have kids, but I know a lot of people who have a lot of kids bli ayin hora, and no one I know has a harness, and they seem to manage. And this has been going on for centuries (I think since the world began). I’m not saying it’s necessarily a problem to use a harness (I don’t feel qualified to have a definitive opinion on the subject, esp. since I’ve never seen it used), but to me, the concept is a chiddush, and it’s hard for me to see how much freedom the kid has if he is on a harness. But, I could be wrong.
