The best goodbye is never saying goodbye. I’ve remained incredibly close to all but one of my former nanny-families. Visits, birthday parties, dinners, FaceTime calls, holidays - everything. Plus I’m available for emergencies and the kids aren’t traumatized. I truly love the kids and I think they’ve all benefitted from knowing that their love and trust in me was well founded. It definitely helps the last day when the kids could say to Nanny, “okay, I’ll see you on Friday!”.
You sound like a great employer and parent, OP. What you’ve come up with is great! I’m sure she’ll be touched
