Our solution? Pool noodles. Yes, that's right. Pool noodles.
Stuffed expertly under the ends of my couches, they prevent the toys, pacifiers, stray socks, dirt, dust, and pet hair from ending up under there. And whats nice is that they can be found at the dollar store and grocery store! We purchased four red ones at our local Publix for $1.99 each. Now I am sure you could probably color them somehow- paint or something, maybe even cover them in coordinating fabrics, but I left mine as is. I don't mind the colors so much- or I am just too lazy to worry about them blending in I guess. But here is a solution all you momma's can grab.
