I know this may sound silly but I have had a few times some redness on my LO (13 mths) skin on the nappy area which I thought it could be related to a build up of soap on the nappies. So, in addition to my normal 60o wash I have then been doing an extra ?delicate/wool? wash (OR just giving the nappies an extra spin on the delicate wash) without any soap so I could get rid of any soap left on the nappies. A bit paranoid, I know, but I wanted to make sure I was not risking leaving red marks on him again, IYSWIM. However I realise that this may cause my nappies to ?wear? quite fast since I have been washing then more than they actually need. How much soap do you use to wash your real nappies, and how do I know there is a build up of soap on them? If I use a reasonable amount of soap do I need to do an extra wash without soap from time to time, and if so how often? Sorry about so many questions?
