Another baby-paraphernalia post, but in case anyone is a) interested and b) in Australia, Woolworths Select brand wet wipes are the free-est from chemical nasties. I wouldn’t advise munching on them (much to Small Boy’s intense displeasure – he loves the things and will hunt down the packets with ridiculous focus), and there are a bunch of ingredients listed as skin irritants, but nothing actually toxic in and of itself, and nothing carcinogenic, and nothing listed as an environmental toxin.
Double check for yourself at www.ewg.org/skindeep, of course, but I’m happy enough with this as an alternative to flannels and spray (which I do still use, but let’s face it, there are some nappy changes where you really want to be able to just toss everything away >.<).
