From her selfies to her body to her fash sense, she's always being criticised and a couple of months ago it was her parenting style that came under fire.
“I am not trying to be sanctimommish, but why isn’t the youngest Kardashian-West rear facing in his car seat? It’s is the law here,” wrote one person on Facebook.
“That kid would be safer in a rear-facing seat, please get informed!” Said another.
Now, Kimmy K has hit back at the haters by uploading a video entitled "Facts" to her Kim Kardashian West app.
"They say for his age he should be rear-facing, but what people didn't know is that Saint is now the weight and the height requirement to sit forward-facing," Kardashian West, 36, explained.
"Saint actually weighs more than North, if that is believable. He does and it is wild — he's huge and he's tall and he's really solid. He's so heavy when you pick him up."
She adds: "It's so crazy that people are so quick to mommy-shame when it's like, I'm just learning it, too, so if anything, maybe people should be like, 'Hey Kim, mom tip: Here is what you should be doing,' not like, 'Oh my god, let's attack her.'"
"But if I was doing something wrong that wasn't approved by my doctor, I would completely change it and I would want someone to tell me, like, hey, that's not appropriate."
Take that, haters!
