For ages, I used to carry wet wipes in a small tupperware container but found that I was leaving them in the bag wet for days on end and they'd get gross. (that was before i had a definite nappy bag though)
I then started carrying dry wipes in a zip up purse (along with a spare snappy, some of that alcohol handwash stuff and a little tub of aromababy bottom balm) and a separate bottle of water. We did that for almost a year without any dramas.
Earlier this year I developed an addiction to commercial wipes (where's the shame emoticon? lol) when we were travelling. (It was camping that started it, then I relapsed again when we went to Thailand.) I was still using cloth on DD's bottom but starting using single use wipes for other things... highchairs, hands, tables, cutlery...
In order to fight my addiction, I have recently started carrying wet (cloth) wipes around again, but this time in a Huggies travel case. And it's working.
There, I've outed myself. My name is Emma and I am a recovering single-use wipes addict.
