I did it! I gave her a notecard where I wrote my wish for her to have a great vacation. I signed it my name,(adult). I didn't let her open before I left, but I did explain that it was from the adult me. I even allowed myself to give her a hug (and receive one!). I'm going to miss her so much, but if I can keep my "adult mind" attitudes then I will be ok. (I have a hunch the littles are going to get pretty upset at some time, maybe my adult can talk to them?)
Anyway, thanks so much for your input. I may be asking for help getting through the next 3 weeks, I'll let you know.
for everyone!
