we started using lux or grated velvet soap ( when we were feeling energetic) with a couple of drops of eucaliptus but it turns out my sensitive little man is allergic to soap !! poor lil guy i started buying this super concentrated organic stuff from the health food shop that smelled like lavender this was expensive but like i said really concentrated i also put a teeny bit of vinegar in the rinse water of his nappise ( no the clothes didnt smell like vinegar) it just neutralises the chemicals if i used adult washing liquid and mad sure i rinsed them again afterwards
