Cure for an Overbearing Nanny?

I hired a nanny and paid an agency for the placement of a seasoned nanny with many years of nanny experience, including multiples. She started six weeks ago, she overlapped two days with the baby nurse. All signs pointed to greatness, initially.

And then, I realized what an expert she is and what a novice I am. I am game to learn things. I read. The baby nurse literally massaged my breasts to keep milk flowing.

The way she interjects her opinions or looks at me when the baby is crying, it borders on insulting. She is however really good at what she does, incredibly punctual, neat as a pin and quiet and unobtrusive, excepting when I have one of the children.

I think an example might be effective. I had just nursed baby two and he was a little fussy. I was holding him on my chest and patting him on his back. She told me, "he's still hungry."  I said, "I thought he was done.". She said "no, no, no, that is the cry of a hungry baby." Then she told me to "try again.". She also has told me that I need to talk about supplementing more formula, but the way she says it, it is almost as if breast milk is silly. She also noted one of the baby's ears was red and asked me, "have you been rooting around in his ear?" I said, "no". She said, "I saw some cotton swabs in the garbage in the nursery. You're just going to pack it in tight. That will make him stir with a big fuss." Then when I am eating something like cheeze puffs, she looks at me with a tight lipped smile and says, "I would be happy to make you some cheese and crackers, something good for your body."

Having given those examples, I have tolerated it this far because she is so good with the babies and because I hope to go back to work in three months. I don't want to start over with a new nanny when I have such a capable one here, even though she is a bit much to bear. Do I just suck it up, knowing that it will serve me better when I am away from the house 11 hours a day?

Anyone?
