It always appears women really hate other women they feel are better than them, most males couldn't care less if you look like a "battle ground" after giving birth, nor will most men remember Kate looking good coming out of hospital. It's more of a day to day thing, we won't hold it against you if you look like a "battleground" for a week, we'll forget soon enough. It's not that important in the grand scheme of things. She sounds crazy with her criticism to be honest.
