Bella Bear : I'm Late to this thread - but as a health prof [please forget this fact as soon as I leave this thread. Mostly I'm a knackered mum and hormonal pregnant whale ] I'd say defo defo defo stop using the baby wipes - going back up to your origional posting.
When they were first marketed they were marketed as use and wash off and dry. The product was not intended to be left on the skin when the babywipe idea was born.
The ideas above about the tea are brill. The honey too - you can just smear it on. Sticky bliss. Manuka deffo, or local if you have any little small holding type enterprise that have bee's. These ideas aply to any type of nappy use.
We did this to make using the tea as easy as wipes for us all:
Make chamomile tea, leave a cereal size bowl of it anywhere you change babba, and put some in a little bottle or a travel spray thing to take out. Use it as water with cotton wool or a bit of soft anything, sheet, pillow case torn up, fleece, anything
Dry area and be nappyless any time this is possible, including house, carseat, pushchair etc. Creative use of pampers bed time dry sheet things!! Look to have most of day without a nappy.
This is hardcore fresh air treatment!!
Get it swabbed by the Gp or Health Visitor - simply ask them to do it, listen to their opinions and ideas, then ask them to do it again. Keep repeating this until its done - and I mean in one consultation. Don't find yourself leaving with another idea to try - get the swab and another idea! Then you will either get a diagnosis and correct treatment [will take about 4 days to get the smaple grown in labs] or get no growth. If there is a lurgy still keep up the soothing chamomile, but the correct treatment will nail the bug quickly. Any cleaning 'product' will strip off oil and healing balm your ds has made, open tiny cracks where scabs are forming invisably and mean the bug just gets to start again. Even water, but chamomile should help the skin to sort of back off it's inflamatory response. They have to have the urine cleaned off afterall!!
Go when it's flared, so there is a good chance of catching a sample of any bug. Use any appointment you have to, emergency, HV, midwife, nurse - anyone can swab. You could even plan in advance - ask Gp to talk you through collecting a swab and do it yourself during a flare up.
If there is no lurgy, it's about management of what may be an ongoing battle you have to wage war on. For me, the fact that these things go when potty trained shows it's to do with freash air and intolerence to 'cleaning', however its done.
Sorry to drone! I have experience of this and this was how it panned out for us!! Got a soapbox as big as my dd1!! We ended up bathing her once a month only {as per several bits of research suggest, royal college of dermatologists back this so I'm not just lazy They reckon move to weekly when crawling ]
