The 40-year-old Celebrity Mum of the Year nominee is known for her controversial views on parents and in her latest tirade says that breast feeding isn't the best the thing you can do for your children.
The mother-of-three said parenting is different for everyone, and that one mother's technique isn't necessarily inferior to another's.
Writing in Now! magazine, she said: "Ultimately, there is no one model for what's right. And there certainly isn't a version which is wrong – no matter what the Mumsnet mafia might want you to believe.
"Breastfeeding does not make you a better mum. Breast may rhyme with best, but paedo rhymes with Speedo and those two things are very wrong indeed."
Katie says the only thing mums can do is their very best.
She continued: "To discover you are all grown up and your mum is actually your best friend is a brilliant thing.
"There are no friends you will make in life who will know you better – and no friends who will love you more.
"I never want to be the sort of mum who will ask anything of my children when I am older. But I can hope."
Katie said that a good mum will accept their child for whoever they are.
She said: "Unlike Facebook, Instagram or Snapchat, your mother will never expect you to have a life which is somehow fantastic or endlessly filled with excitement."
The former Celebrity Big Brother's contestant's views come as a Brazilian study found that breastfed babies grow up to have higher IQs.
Researchers found that the longer mums breastfeed their infants the more likely they are to grow up into well-educated and higher-earning adults.
Nearly 3,500 them were then invited to sit IQ tests at the age of 30.
Those who had been breastfed proved to be more intelligent, had spent longer at school and earned more than those who had not been. And the longer they were breastfed as a baby, the more high achieving they were.
