You tried to be sarcastic, but told the truth instead. The way you talk tells me that you are ignorant to the gigantic shift in one's day to day life and mindset having a child is.
It's something one cannot grasp as non-parent because it involves feelings and states.of mind that do not usually appear in a life without children.
So no, just as a psychologist will not dare to have opinions on how someone deals with grief, they can and will not have opinions about how parents do parenting.
Everyone who tries to push their agenda onto parents without being involved themselves is a hypocrite and nothing more.
Believe it or not, there are areas of life you aren't entitled to voice your opinions about without looking like a dork of the first order.
