Ahhh, Milestones

Did anyone else hit their thirties and realize that sleeping in the floor with the kids is just no longer an option. As a kid, I was booted out of my bed many times for out-of-town company, and, honestly, I'd usually just cram myself in a bed with my sisters, but sometimes I got sent to the floor. I thought it was just out of consideration and hospitality for our guests, but I now realize that those guests wouldn't have been able to walk the next day had they been the ones sent to the floor. I tried to "camp out" with the kids in the living room the other night, but after they all fell asleep, I had to sneak back to my bed. I know good and well that I am NOT bonier than I used to be (if anything, the bones are now more cushioned by a nice layer of fat), but I never realized how every bone in your body can dig into the floor at one time. So, not only is the floor just not an option any more, but my bed isn't cutting it as well, either. I don't think it's any less comfortable than it was a couple of years ago, but for some reason I'm waking up several times a night with my arm or leg asleep or my neck in a terrible position, and then it's almost like I creak out of bed in the morning. What's up with that?! Am I prematurely aging, or is this normal? And, please don't give me the speech about vitamins and exercise and junk like that. I've heard it from all those related to me who are now in their fifties - another milestone I have to look forward to, I suppose. If that's my only option, I'll just have to wait until my 50's when the kids are gone like you all did!!!
