Why Do We Shame Mothers with Many Children?

I was reading a fb post on a mom being shamed for having alot of kids.....first of all off the beginning I praise that mom seriously I gave birth 2x and hope I never have to feel that pain again. Second of all you got to be a very patient mom because having many kids truly makes you have extra work bathing cleaning cooking dishes laundry kid mood swings that already puts you in my eyes are a hero! Third you are blessed to be able to have all your beautiful kids with their own personality and uniqueness into your life. I disagree with shaming mothers of multiple children I fully put my hat down for anyone who had many kids it's hard enough for me with only 2!!!!!
