I need a Wife!

I ask myself this everyday, "How do I get it all done?"  I've got the basics down, and now that I'm getting a lot of help from my husband, laundry is under control.  Here is the dilemma...my kids!  Now, don't get me wrong, I love them dearly, but boy, they sure do make a big mess.  From the playroom downstairs, to their clothes, the bathroom (really, is it that hard to wipe your toothpaste off the sink when you finish brushing?) and there is only one of me.  My husband is the world's worse at playing when you should be getting chores done (if anyone thinks that their husband is worse, I want to hear stories!!) so he doesn't help in the time management of it all.  He says, "Don't worry about it.  I'll get it tomorrow." Then tomorrow comes and goes, and the mess is still there.  I know that parenting has changed a bunch since I was young, but I remember doing chores.  Everyday, I had to set and clear the table.  Make my lunch.  Help fold laundry.  Dust/vaccuum/clean the bathroom on the weekends.  At the time I thought that I had the meanest mom ever for making us to all of the housework.  As a mom, I understand where my mom was coming from, you have to ask for help if you are going to keep up with the clutter.  Is it wrong of me to give my children age appropriate chores to help me out around the house?  Am I the mean evil step mom if I ask my stepson to help out?  I don't think so, but I am sure there are some differing opinions out there.  Oh, well, until I can afford a full time housekeeper, the kids will have to do!
