ds is 14 months and has been teething quite badly for a couple of weeks. just before he started teething he got a nappy rash. every nappy change i apply lavender oil and then metanium but it is only taking the redness away and not completely clearing the rash. it keeps flaring up. also up until about 2/3 weeks ago i was using cloth and washable wipes but i needed a break from washing them so got a packet of wipes and disposable nappies. could this be prolonging it? should i go back to cloth? and what should i use to clear the rash now since metanium isn't working. it always did before.
