I agree with B. And I thought it was rude to call this issue with the nanny a first world problem. (I haven't looked back to see who said it, so I'm not making this personal about whoever wrote it...)
A nanny is like DAYCARE. If the nanny doesn't come, working parents have to make alternative arrangements, and that might mean paying someone else to watch the kids, and pay double. I don't know why someone would be dismissive of it, as if it's not important. And trying to come up with a solution that works for the family, and NOT just for the nanny isn't something to fuss at the parent for...
Yeah, I do see some rather trivial problems mentioned here sometimes, but unless it's a troll or a SWH that's screaming at people, I don't usually diss the question as if it's not important enough to ask (well, except for "I had unprotected sex. Could I be pregnant?" Especially when the poster asks over and over, grrrr....)
