I am a nanny to two boys aged 4 and 6, and I take my own child to work, aged 2. For me and my employers it works great. The boys adore my dd and think of her as a sister,its like having one without actually having one, if you see what I mean.
I treat all the children the same , theres definately no favouritism, I'm paid to do a job and thats exactly what I do.
I am lucky that my boss has let me use all her stuff i.e haighchairs, in the past but I wouldve taken my own. She very kindly provides lunch for my dd too.
It probably works so well because I was employed by them before I was pregnant so we had already built up a strong relationship. But since I have had dd , I can recognise that I am much better at my job. Now that I am a mum, I know exactly how my boss feels about her children , allowing me to do my job better.
I would definately consider taking a nanny with her own child lasvegaas, why dont you ask for a trial first to make sure? I,m sure the prospective nannys would welcome that.
good luck
