S. -
You've already made the decision, you don't want to keep her, so maybe you're just looking for confirmation (?) The only good thing you said about her is that she shows up when she says she will. This is not in my top 3 list of someone to watch my child (it's important, sure, but if I had to choose between a great nanny who always ran late and a bad one that was prompt, I'm going with the great one and I'll just start telling her she needs to be there at an earlier time than I really need her)
I had a nanny for my son when I first went back to work and I never once felt uncomfortable about what they did during the day. I don't think it is normal to feel the way you do toward your nanny. Sure you could sit with her and go over things, but honestly, from your post, again, the only redeeming quality you've put out to us is that she's on time. And that's just not sounding like a good deal, you know? If there was just one area of frustration, like your daughter's hair being a mess, then great - sit down and hash that out - but it sounds as if you'd be sitting down and asking her just to be someone completely different than who she is. That's not fair to you, her, or your daughter. So maybe you should just cut your losses and find someone that you can establish a better rapport with.
It's very tough, though, because the prospect of finding new care is overwhelming and is probably hindering your decision. Don't let it. Just as we somehow find money in our budgets to afford babies we were sure we couldn't, you will find the time in your schedule to find a better care situation for your daughter.
Good luck!
