As someone with a kid I must say it’s a nonsense.

It helps to align your life, your priorities in some healthy way, yes.

But its far from fulfilling any voids in your soul.

And i warn anyone who would think to treat kids as a solution to their mental issues — this is the most effective path to misery and a damaged child’s psyche. Because children subconsciously sense things like that and this puts unbearable pressure on them, whether you communicate it explicitly or not.
