Carissa, I feel the same way....dh and I are almost at the complete opposite end of the scale parent wise, we hardly EVER get out, and if and when we do these days we always have Aynsley.
A few weeks ago I went over to visit my parents and had some errands to do so we all stayed with my parents and then I left the boys for a few days....it was AWESOME! ( they live about 3 hours and a ferry ride away )
I completely do let the boys go off for a few days now and then with grandparents, but by no means am I ( or dh ) out partying....I have been preggo or nursing for over 5 years straight

there is no partying going on - believe me

AND I have never been a huge partier ( unless you count being 16 )
Anyways, I guess maybe me "ditching " my kids for a few days now and then is selfish, but I enjoy the time as do my parents ( and my boys

)
