9 times out of 10 it doesn't all get done! There - that's my secret!! But I wake up at 4:15 - drop the kid off at 6:00 - and I'm not back back at home until about 5:00. That gives me 3.5 hours with her - including time to cook dinner, clean the mess and give her a bath. I'll be damned if I'm going to spend the only time I get with her scrubbng the floor!! I generally clean when she goes to bed at 8:30 - but I need a little down time, too - and I don't go to bed until about 11:00.
In a nutshell, no one is going to get sick or die if a few toys sit in the middle of the living room floor overnight, or if the kitchen floor doesn't get swept for an extra day. I don't live in a pigstye AT ALL - but I do it all and sometimes I run out of steam!
