Nanny Woes

So I thought it would be a great idea to have people I know watch my daughter while I went back to work. I guess that is what I get for thinking. I have a huge mess on my hands with more family and friend drama than I ever asked for!! I hired my husband's little brother's girlfriend (say that 3 times fast) to be my nanny three days a week and then my husband and I got the sneaking feeling that my daughter was spending too much time in the swing because everytime either of us walked in unannounced she was in the swing. So I mentioned to the nanny that my daughter didn't need to spend too much time in the swing......ya know we want her to roll over and crawl and stuff too. Then at 4 months she's not even attempting to roll over yet so I decide to set up a nanny cam just to see how much time she was spending in the swing and what I saw was shocking!! I kid you not if my daughter was not having a bottle or in bed for her nap she was in that swing all day, while my "nanny", and I use that word loosely, sat on the couch and text messaged her friends, changed her facebook status and made a cleaning list for herself when she got home. I was so mad I was shaking. I wondered, would the courts go lighter on me for hurting her because I did it in a fit of rage being a mean momma bear???? So now I have to fire the "almost" sister-in-law and try and keep my husband and his brother on good terms at the same time. I called her and told her about the nanny cam and told her we were sorry it had to end like this but we would be using someone else. My husband's brother eventually called and they got in to a huge fight, he was stating that you don't treat family that way.......Well what is my daughter, chopped liver? You don't treat family that way either but she did!! I am not really sure but I would bet that there is someone I could call to make sure she never does that to anyone else's kid that she nanny's for!!
