We usually use baby love nappies on bub but recently they've been sticking to his bum, balls and penis, we normally put some sudocream to stop the sticking but tonight they stuck so bad they pulled skin off his penis and left blisters on his bum, he's in so much pain :( anyone have any ideas on what we could use to get rise of the sores? We have changed nappy brand and will buy new ones tomorrow but in the meantime what can I do?
