Oh I don't know, if I start to write it down it just looks petty and silly. It is unfortunate that she is taking over from another lady we had before Christmas as emergency cover who absolutely lovely. This new one has been doing it for 20 years so is full of stories about past babies she's looked after; she also has a fantastically annoying way of speaking: if you tell her anything she just replies "yup yup yup" and is starting to sound like a small yappy dog. She also says "like" every other word which is (like) very annoying. I know we should be grateful to have her and many people would kill to have help and I'm being snobby and intolerant but.........I just hope she doesn't read mumsnet.
I think if she has only been there a day you need to give her a chance. Could you share the care of the baby. I've had clients who I rarely see or other clients I spend a lot of time with, (particularly mums of first babies).
You would need to pay her, so unless you can afford it I would put up with her.
