The mumsnet nappy hacks video, surely if you use a make up brush to apply nappy cream because 'washing your hands after applying cream is abit of a pain', you would have to wash the brush thoroughly which would possibly take longer? Or do you leave the brush sitting around with old cream on it? Who does a nappy change etc without washing hands anyway?
No offence intended. Just seems random, pointless and rather unhygienic to me. Each to their own I guess.
