Yep, will hit the containers with natural disso today Good sunshine here in Tassie this week. Should stripwash my stash too!

No lotions and potions used here, water with the odd drop of essential oil is the most I ever use. Paw paw ointment is all that goes on her bum (really resisting the zinc creams... is amolin the most 'natural'?)
And Cheeky Wipes is not anything high tech or heated Just a pile of fine cotton terry towels (15cm sq) in a box with water and scent. I suspect the issue was more with heating the room for comfort.

Great replies ladies, thanks so much for your support. I will give DD more nappy free time today and keep an eye on the redness.
