Our next door neighbor told me a hair raising story about a murder at the next house down, before it was renovated and sold. The owner had a grandchild living in the basement. The grandchild was a bad seed, started stealing - cashing social security checks - and then used the money to host a big unsanctioned party that got out of control. At the party a fight brought out, something to do with drugs or money - and the grandchild ended up getting her throat slashed by another party "guest." She made it out to the street before she died.
So no I would not feel bad about reporting the nanny or getting her fired if that is what happens.

This nanny is irresponsible, and in my opinion she should be fired. You should take care before choosing nanny’s. It is better to seek the help of an agency for the perfect selection. We had chosen our live-out caregivers from the best nanny agency in Toronto. We are really satisfied with her service. The nanny’s with strong agency backup will always show responsibility and respect towards the family. It is safe too.
