Marion is visiting me right now with her girls and Elise is sick and waking up during the night and my boys are learning how to sleep in their crib vs. carseats.  Tess is fantastic at sleeping all night, but she may be the only one.  We have discussed the need for a night nanny multiple times in order for us to function.  :)  Remember in college when if we didn't get enough sleep we just didn't go to class?  Bliss.
