Some real nappy websites I've looked at seem to suggest that its OK to not use wraps over cloth nappies during the day, to allow the skin to breathe better. Has anyone actually tried this with a crawling baby? I suppose it might be OK if you were at home and just dressed the baby in a nappy and T-shirt and kept checking regularly for dampness? My DS is 8 months now, and I use a mixture of Tots Bots and Motherease nappies, but he has started to get nappy rash so I'm wondering if leaving off the wraps would help?
