ultra sound isnt bad at all. and if you want diapers that bad, and your parents wont buy them for you, buy them yourself. I was really nervous about it at first, but just go out and buy them where people you know dont live. thats what I do. and if your parents complain tell them you are tired of protection that leaks. My parents bought me generic (target)diapers and they leaked terrible. so I asked for something better, and they bought walgreens. ughhhh!! I know how you feel. So I went out and bought my own. I bought depends overnight and they barely leaked once or maybe twice. and they bought me those for a lttle while, and then my wetting started to go away at night and I Tried the expensive TENA diapers that I found at wall-mart. and I wear those at night. if you dont "use them" the you can take them off and save them for the next night thay hold more than anything I have ever tried before.
