My little 6 month old boy always wets through at night. It is really hard to change him when he is asleep as it goes through to the matress protecter, sheets, sleeping bag, his pj's and his positioning coushins. By the time i have changed all of this, he wakes up. I have tried all different brands of nappies, and larger ones as well but he seems to always wet up his back! I have seen those cotton pants but they have pvc lining, not sure if they are good for the skin to breathe? has anyone got any suggestions??
