I am not an eco mum at all, but I am a nanny and had experience with both washable nappies and disposables, and with wipes.
From an expert point of view I would say to any mum, never use baby wipes on your baby.
If you want to, do this experiment. Buy a pack of babywipes and every 3 hours for 24 hours wipe your face all over and don't wash it off. You will soon see, you face will be very red, spotty and starting to get sore. Your new babies bottom is more delicate than your face by far.
I started with the pampers lark as a new mum, by 7 weeks of very bad nappy rash I stopped. I thought, would I want someone to rub chemicals all over my bottom constantly all day long, I actually thought, well no.
Beauticians tell us not to put all this harsh stuff on our faces and what damage it does, do you really think your baby can cope with it.
I switched to nature babies wipes and nappies, nature babies still gave my baby a slightly red bottom, then bought motherease washable nappies I use with a travel spray bottle of water and some one life flushable nappy linners, these are great, they literally look like a dry babywipe.
I still use nature babies nappies, but never would I use a baby wipe on my children again, and I only use an organic bath wash and bath every other night.
I would say to any mum, from a mum who since using onelife nappy linners and water, with either washable nappies or nature babies nappies, my baby has never ever had nappy rash once since, I never even use cream on her bottom, I think that says it all really.
