I've been a nanny for 20 years and yes, and as much as people don't want to believe it. We do raise your children. When I'm there from 7:30am-8 pm because you're on business trips or you have to work late. When I hear the first word or the first step. When I am the one helping with the homework. That's not the parent raising the child, that's the babysitter, nanny or child-care provider.
You need help raising your kids, and that's fine, but don't act like we're just the paid help. We definetely work to make sure your children are well cared while you work.
