'I can't provide for them the way I wish I could': 4 women share the realities of parenthood

"What I wish I had known about parenting before I had kids was that everything is your fault," says 45-year-old Tami. "Not only from the public's perspective, but your kids believe it, too. I know they love and appreciate what I do, but it doesn't stop them from being brutally honest about my failings."
