I just think....hmmm plastic....hmmm everything down there must be 'cooking' no wonder my boys had so much nappy rash. Im so use to Vy having a big butt, I couldnt imagine her without it now. And what ediction would I have to find to fill my empty void if it wasnt for cloth nappies, covers, material to make them...ahhh I dont even want to think about it!!!!!
