Thank you everyone for your support and truthful opinions, it means a great deal to me. And thank you to all of those that have PM'ed me as well. I truly feel supported here on the DIS.
I've read all the different replies, and I agree with all of you that say those first few days are critical! We are in Oklahoma, Ft. Sill, which is huge - so most, if not all, of the schools in the area are military oriented. I talked to my DH tonight, and finally got him to see my point of view (for once, lol). School starts on friday august 21st, so we'll see if we can schedule to leave (we're driving) the thursday after, and they will be missing a week of school. I asked about Labor Day weekend, but Labor Day is on the 7th this year, and DH starts at his new unit on september 10th. It will be cutting it very close, and he doesn't want to risk it.
The very first day of school I will be sending in a note about them being absent, and will be keeping a journal of each day, etc. The did that the last time we went.
Dh won't be here during the limited school breaks that OK has, so this is really the only time we have to go. We're just waiting to confirm dates so I can start planning again. So stressful!!!
I am not worried about them missing school because they really won't be deep into anything at that point and they are smart kids.
I'm really surprised that this thread hasn't been closed yet! ha ha ha
