I think the ss ot is a bit odd. we have started hoisting dd and I noticed her bath sling was rubbing around her groin area. so I told the ot. she rang the sling company and then phoned me to ask if I could send them a photo of the affected area!!!!!!!!!!!!!! Surprise surprise I said no. so now dh is going to draw a diagram.(dd is 11 by the way) just thought this might amuse you
