Ok, I know this may sound a bit 'out there', but start
telling her now that she's going to be staying with your daughter and how much fun she's going to have and that you will miss her while you are gone and that you are coming back and can't wait to hear about all the great things she did while you were away. Be upbeat and excited and positive about it. Have a very happy, calm attitude when you drop her off. A hug and kiss when you leave, no big production. IMHO it's just really important for YOU to not be stressed or upset, Daisy will pick up on that quicker then anything.
Have a great vacation, you know Daisy will be well taken care of.
