I used to HATE when people gatekeep parenting. Stories of mums or dads being like "Oh you don't know what tired is you don't have to have kids". Swore I wasnt gonna do that. Who am I to say you arnt tired because you have a different experience to me? But I just had a friend try to tell me something about parenting, about the sacrifices you do or don't have to make. And I just wanted to laugh in his face. He isn't a dad. He would not have a clue the sacrifices required, or the decisions you face on the daily. I'm sure it came from the best of intentions, but it felt like a Call Of Duty player telling an Army Officer he was shooting wrong. In the end I decided to walk away, because "Bro you're not a dad you are talking completely out of your ass and its condescending AF" is usually a friendship killer.
So I think maybe we're all best off just sticking to our own lanes a bit more. There's no way for a parent to say "this is hard" in a way that isnt off-putting to non parents, and its hard for non-parents to offer advice that doesn't sound like someone who read web MD trying to advise a surgeon.
