I'll be using something this time.. my waters broke early at home, and in a big way! I reckon it would soak through towels pretty quick. Who knows if it'll happen again.. but I'm not taking a chance! LOL. I'll be sitting on towels tho everywhere I go from about 37 weeks I think!

You can get waterproof matress protectors pretty cheap. They're a bit sweaty to sleep on .. but might be worth it if you're worried
