I always tell my charges that they will always be in my life and can still be my vey special friends, but now they have a chance to make a new friend. There will probably be some things about me that they miss, but there will be some things that they like better about the new person. I usually ask them which things they hope the new person will do the same as I, and which they hope will be different. My last job, the preschooler hoped that the new nanny would sings songs to her (like me) and give her candy every day (unlike me)!
