I'm a single mom of two girls (8 and 5), and I work full-time. I had a babysitter over the summer so my girls could enjoy the summer at home with their friends. I, too, struggled with the mess that accumulated while I was at work all day...and cleaning was the last thing I wanted to do in the evenings.
Yes, our children are only young once, and they deserve to play and have fun. BUT -- we parents also deserve to enjoy the homes we work so hard to afford. I (and it sounds like I'm not alone) cannot relax in a messy home. So here are some of my favorite tips:
1. I love Clorox bleach tablets. You put one in the toilet tank every few months, and that's it. Your toilet stays clean and your bathroom smells bleachy-clean all the time. Sure, you have to wipe the seat every few days, but that's easy.
2. I love any wipes (Clorox, Windex, Pledge, etc.) They're probably more expensive, but I guess I value the convenience. I wipe down my bathroom sink and mirrors while I'm brushing my teeth in the morning. I turn my girls loose with the Pledge wipes. They have a blast, and I get my furniture dusted.
3. Focus your cleaning efforts on the common living area. Unexpected guests aren't going to venture into your bedroom.
4. Limit toys to one room...preferably one with a door that can be shut when unexpected guests show up!! If possible, keep toys out of bedrooms, and especially out of YOUR bedroom and the common living area. You deserve to have grown-up space.
5. Teach your little ones to put their toys away. At their ages, they're going to need help with this, but you can make a game out of it and offer a reward for helping.
6. Invest in stackable storage containers. I especially like the ones with drawers. Buy the clear plastic ones so you (and the girls) can see what's in them. It will help you organize all of those little toys, it will save space, and it's more visually appealing than random toys laying all over the floor.
7. Stay on top of it. The more you put off, the more overwhelming the task.
8. Do one load of laundry each day, rather than saving it all for "laundry day". Wash it, dry it, and put it away immediately. Dryer to drawer. Avoid laundry baskets.
9. Use paper plates and cups at lunchtime. One less stack of dishes to do.
I hope this helps!!
