Mommy guilt

I'm torn. This weekend is our annual Duff girls' weekend. I am thrilled to be going, it's always a fun time and we get to be silly and eat a lot and go to some cultural/community thing we never do otherwise. This year I'm a mommy and I have been telling myself, oh yes, no problem, I'm so happy to have a couple days to do adult stuff, whoopee!
Mom & Dad are coming to stay with the babies for the weekend and Mom wanted me to write down their routine and whatever other stuff they need to know. Routine? Ha. But I did start making a few notes, and the more I do, the more I am starting to miss them before I even leave, and I feel guilty for going away when I could be spending time with them, etc etc etc. I guess it just comes with the territory. There's all these little things we do that I guess are routine for us, even if it's just a certain way we get them ready for bed or play with them, or whatever.
But then I tell myself it's only once a year, and they'll live, and they love Papa and Grandma, and they love the babies, and they'll be in good hands and I'm just being a drama queen. I guess.
So if you see my babies this weekend give them a kiss for me.
