It *could* still be teeth...
in that Zeke would cut 2-4 at the same time and often in a row iykwim,
doesn't have to be one at a time.
Also here for Brooke (who was in squares and didn't have nappy rash) kiwi fruit was the culprit - one a day was the maximum because otherwise the poo seriously burnt out your nostril hairs lol so def not good for her bum.
the other thing is it only takes one time - you know, and even the most diligent person it only takes one time in whatever nappy (happens to kids in disposables too) for that 'burn' to happen and then the skin is weaker/more susceptable iykwim.
If the benefit that the disposables are providing is to keep his bum overly-dry (normally a negative) then I guess look for what can do that for you in cloth.
For us fleece and cornflour worked very well. Zeke's bum got like that with teeth but Brooke and Jake despite teeth and all the rest really never had nappy rash. Brooke and Jake were (mostly) terries and Zeke in MCN.
If what you're saying is that cloth in the day is fine but it's the overnight that's the prob, then I'd say it's not cloth as such (otherwise you'd see the same prob in the day) rather it's the time the skin spends in contact with ______ overnight - could be the nappy fibre, the pee, detergent residue, teeth or combination of any one of those or something else totally.
If you're game (does he poo at night?) you could try the no nappy overnight with the bed/cot prepped - ie fleece jumper, fleece pants, fleece layer on the bed (offcut from Spotlight/wherever), then under that the towels for absorbency etc - so he can be nappy-free at night too?
Another way to maybe see whether it's a fibre/material is to cut a fleece liner in half, lay it on one side of the nappy only, and have him in that overnight - and even if it moves you'll still tell where it was touching the skin or not... you could try the same idea in a single nappy (ie not half fleece liner) with a barrier cream on one side his bum, and cornflour on the other
iykwim - because it's hard to 'see' the variables when you try something different each night?
Zeke did go through a brief stage where it didn't matter what was on his bum (and he was mostly nappy free), he got red - so it wouldn't matter cloth/fleece/not fleece/nappy free (never used disposables with him but I fig nappy free was better anyway) it just took the slightest thing - and then bang, no more. So I never really worked out what it was - just nappy free, cornflour and fleece liner...
Brooke and Jake were in mostly terries and never rashed so I think it's partly whatever variable in the kid themselves... yk?
anyway yes it is way frustrating when you don't know what's causing it
hope you find the answer soon
