It will get harder as your girls get older. Unless you don't mind pulling them from school. I was not OK pulling for more than 2 days in a row. My kids were top of the class students, so it is not like they would fall behind, but they just didn't want to have to make up work. And our High school policy is more than 3 days absent and they take finals, so they also didn't want to miss because of that. Add in that our school district refuses to put out our school calendar until the end of the school year, we just now got our next years schedule, super frustrating. Add in sports, mandatory practices, tournaments, mandatory band camp, and and and it was super hard to plan ahead! Our Yellowstone trip, that I already was way behind in planning for this July, was able to snag some in park rooms just last month is already in jeopardy of being cancelled. If DD does this Australia thing it totally messes up my plans. She would fly back home while we were in middle of trip. Grrrrrr I can't plan anything in advance. Trying to see if I can rearrange some things, fly into SLC instead of Denver, but it is super pricey. And I still think it may just be DH and I. Oldest DD won't be back, other DD will be working and DS is still waiting to hear from a summer job he applied for.
