You are absolutely correct. It's not just the the practice, but the entire premise which is flawed and was always set to fail except perhaps with a tiny, select group of children, if they did not have to live in the real world.
Ineffective parenting (which is what I call Gentle parening) fails from the outset by positioning the child's emotions as the centre of everything, encroaching on other people's right to boundaries, and fostering entitlement and an inability to handle real world behaviours, requirements and challenges.
When you add to that the reality that those who prefer ineffective parenting are usually exactly the people who should be avoiding it, due to their own huge biases in favour of their children and inability to understand that little Jasper is considered a painful pain in the arse by most of those around him, it has been a recipe for disaster.
The Gentle (Ineffective) parents of the world are the dog owners who refuse to put their dog on a leash and keep telling you how friendly their dog is as you try to rescue your terrified baby from their unwanted attentions. They just will not listen.
Excessive emotional accommodation undermines resilience and creates self centred children.
See "Gentle Parenting Is Creating a Generation of Entitled Children” by Louise Roberts, The Telegraph (2024) which documents how child-centered discipline erodes authority and produces demanding, uncooperative behavior.
And "Why Gentle Parenting Backfires” by Dr. John Rosemond, Parenting by the Book newsletter (2023) which cites clinical observations that children raised without clear hierarchy view themselves as the most important person in every interaction.
You will not get any of the ineffective parents to listen to you though, and when their child meets the entirely predictable consequences of their own ineffective parenting, cannot manage socially, is a bully who becomes bullied, is friendless, cannot rself regulate, hold down a job or otherwise has huge struggles because their parent has not raised them to live in a society and they think the universe revolves around their feelings, the parents will blame everyone but themselves.
