DS scratched my nipple earlier and has fed from it a few times since and it's really sore. I am out of Lansinoh and have no way of getting any now, but I have got some Weleda Calendula nappy change cream which has always cleared up nappy rash really quickly, would it be ok to use that? I would wipe it off before feeding him (though hopefully he will not want any more for a while) - he is 15 months old if that is relevant.
