What they said LOL.

I find heat/sweat to be one of the worst things for DS and both nappy rash and heat rash, and use the opposite strategies to what I would use in the dry season. He's been in sposies for the last few months because my morning sickness was not too happy about the nappy bucket, but it has also helped the rash. In the dry season he is almost never rashy, at the moment it will take weeks to clear up even a small spot, even in sposies. Normally he would never get even the slightest bit of rash in sposies, where he might be more prone to it in cloth (many people find it's the opposite).

The tricks I usually use to combat the heat/sweat/rash are:
- very frequent changes
- sudocream (or castor oil/zinc cream from the chemist, same active ingredients without the fragrance) and microfleece liners. Lately I've been using curash (which I hate but until I get some zinc oxide to make my own), which helps to dry him out a bit.
- microfleece liners help wick moisture, but being synthetic, can increase heat.
- when at home, I'll have him in a natural fibre fitted without a cover, then I can change as soon as he's had a wee. Even though he doesn't react to synthetics/PUL, they do increase the 'sweat' factor somewhat in the heat. I've also had to stop putting him in clothes that are not natural fibre when it's hot. Or just have him in a nappy.
- because he often wees overnight or during a day sleep (possibly he has a wee as he is BFing, as he feeds to sleep), I'll either try to dream change him as soon as I put him down, or use sposies for sleep if he is rashy. Otherwise I use the most breathable night nappies I can find, preferably an AIO or fitted with a windpro or wool outer or cover. And slather in barrier cream with a microfleece liner.

In the dry season I wipe with a very damp cloth, moisturise on damp skin (absorbs better), and very rarely need barrier cream. When it's dry the rash seems to be exacerbated by dry skin, in the wet, it's the opposite.

Even if you find you need to use sposies occasionally to help clear up a rash, or for a sleep when it's really really hot, it doesn't mean that your cloth dreams are over. You can use barrier creams with cloth as long as you use a liner, and if you try a few things to see what works best for your DD, you may find you don't even need to resort to sposies at all.
