I have just had to do this, eastnorth, and after agonising over it for several weeks, I just came out and told her that we have decided to change our childcare arrangements. For the reasons you are quoting too: not to need to get them out of the house in the morning (I have 4 boys), the schoolkids coming home after school, the littlies get to play with their own stuff, have their regular daytime sleep times etc etc.
TBH, it went well. I didn't cry - she didn't cry. We had been with her for 8 years and she was a phantastic CM and a lovely person. Thank goodness, we are still friends - not best friends, but I enjoyed a recent lunch out with her
. And she happy to help us out, should we ever need emergency cover, so it's all good.
My top tips:
Tell her at a time when there is no distraction or time pressure.
Tell her face to face.
Don't apologise - you are acting in your DC's/your best interest.
Give her as much notice as you can.
I did not offer her a bonus, but put 2 weeks wages in a Thank-you card which was a lot of money for us, but I was painfully aware that I was removing 4 mindees from her in one fell swoop...
.
And FWIW, we were sad to leave her, the boys still sometimes say they miss her (new nanny apparently 'too strict'
), but 2 months after the changeover I can honsetly say that it was the right decision for us.
Good luck!
