What is most important in these types of situations is for the parent to let the nanny do her job. Simple.
If she is allowed to do her job w/out feeling as if she is being closely monitored by the parent, then it can go smoothly.
I suggest your work space be as far away from her and your child as possible. I also suggest you concentrate 100% on your job and as hard as it is, refrain from interfering with caring for your baby.
This is challenging. If for instance, you hear your baby screaming out and the nanny does not seem able to calm him down, it is only natural as a mother to go see what is the matter.
However, doing this will start a bad habit for you as you may find yourself doing this more and more. Unless your nanny asks for your help specifically, I would just let her handle everything.
Also, let them get outside the house occasionally. Since your baby is so young, I suggest daily stroller walks. It benefits nanny to get some fresh air and exercise while baby gets to feel the motion of the stroller and a change of scenery.
Finally, make sure you and the nanny have good chemistry together and are both on the same page as to respecting boundaries and such.
Have fun and good luck to all of you!
