like pee <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/greensad.gif" style="border:0px solid;" title="greensad"> They all wet the bed and although they wear pull ups or goodnights, the middle 2 end up wetting through. I have ordered some nap e-z and am hoping that will not leak. Anyway, my upstairs where the rooms are smell awful. They have a plastic mattress protector on their bed, so it isn't the mattress. The sheets and blankets get washed when needed. I don't know how to get the smell out??? Any ideas??
