I don't think of myself as a gentle parenting afficionado, I believe children need firm boundaries and parents who aren't afraid to be unpopular. And yet I learned the hard way, through adopting my dc2 who is very disregulated, that traditional parenting just doesn't do it for some kids.
My dd needs high intensity parenting; it is absolutely exhausting. It is also very frustrating in the moment. I have learned that when she is disregulated there is absolutely no point making demands, disciplining or trying to talk to her. I have to be constantly thinking ahead to help her be able to make the right choices, to avoid her feeling cornered.
The sticky part is where it hits the outside world. I'm very aware that I'm preparing her for real life, in which she won't have people smoothing her path. I don't know if I always get it right. But I do know that it is utterly pointless to just expect her to shape up in the way my older child has.
I suppose what I'm doing is therapeutic parenting, which is not the same as lazy parenting. But I think it has enough in common with gentle parenting to make the point that traditional parenting doesn't always work. I'm also intensely annoyed by poorly parented kids, but IME that can happen with strict as well as with gentle parenting.
