I'm sure she will ask if the kids will be in school, where will they be, who will be watching them etc.

I was over analysing (a hobby of mine I really need to ditch) the first message I send. Tell her all the info upfront so she knows how it will go without her potentially flying off the handle and making assumptions. My W and I have both been big time guilty of making lots of assumptions in the past 7 months.
