suggestions for settling toddler with new nanny?

[theory]

DD (2.2) is starting with a new nanny in one week's time, and I'm wondering how best to help her make the transition. She's very attached to the nanny who will be leaving.

I'm thinking we should ask the new person to come spend some time with DD and the current nanny next week- possibly every morning or every other day? (I can't really afford all day every day.) How should we talk to DD about what's going to happen? I've begun to tell her that the new nanny will be coming to see us again, but I haven't mentioned that the old one is leaving. I think she understands that something is up, though; she's been very out of sorts and clingy for the past two weeks (including during interviews). I was thinking we might make a going away present for the old nanny together?

Sounds good for old nanny to do settling in period with new nanny - or if you do the settling in period with the new nanny, would also be good. Going away present for old nanny sounds like a great idea. I would explain the situation to her as soon as possible. Simply and carefully. Make sure she understands (on a basic level) WHY the old nanny is leaving and that you will always be there, the same old mum and/or dad, no matter what. It could take a while for her to settle with the new nanny - but she'll get there in the end.
