My best advice is to take a few days off to decompress if you can. Then move on to the next thing.

At the risk of being opportunistic- OP you sound like a wonderful person- are you by any chance looking for a new position? We are looking for someone wonderful to care for our son !

Try to find a way to still be a part of their lives if possible.

My best advice would be to be a future "date night" sitter for them and if that is not possible, ask the parents if you can stop by for a "friendly visit" every now and then to stay connected to the kiddos.

Thanks everyone! It was a sobfest...but I feel good knowing we have some babysitting dates planned and I'm going to Skype with the kiddos after their first week of preschool.

I know exactly how you feel. When I left my family from another state whom I had been with for 3 years I was so excited (as I was moving to DC) but at the same time I was sad. I too thought I would make it but me and the family had a serious crying session!
I still talk to them till this day. I'm currently with a new family-have been for 2 years and my time will come to an end next Summer.
It will be difficult but realize that you helped them in every way possible and loved the little ones. Be strong! It gets easier.

Nope, you're going to cry. It's a sad day when you leave behind the weekly contact with beloved charges. Just let yourself be sad, that's a normal feeling. Definitely plan to babysit and if you don't hear from them for a while (I don't know how often they need evening care) you can always ask to take the kids out for a special day. I did this with my last charge, we go to the zoo or children's museum every few months. It's been wonderful to maintain this relationship.

So great when the parents allow their child to somehow continue a relationship with the nanny.

Thank you! We've made plans for me to babysit as well.

OP, you sounds like a wonderful care provider. My 3 yr old son is graduating the in-home daycare this Friday as well. He will move to a neighborhood preschool. (But, we already made a plan to return to same care provider for a backup care later in the month).

We, as a parents, also feels emotional knowing my son will leave wonderful individual attention he had been receiving since he was 6 months old.

Today is my last day with my current charges of 3 years whom I've cared for since they were newborns. I thought I would make it through the day without falling apart, but sitting here alone during nap time and I'm beginning to blubber....this is the longest I've ever stayed with a family, and prior to working for them I had the employers from hell. So from any nannies who have been there, how do you pull yourself together after leaving a family, and especially kids that you love, and get excited for your next job? Also any tips for not sobbing at pick up would be appreciated as well!
