Help me identify this rash?

On my 2 year old's bum.

Haven't changed anything in terms of laundry and this appeared throughout today

Looks like the start of chicken pox. It’s rife at the moment here.

I thought that but DH googled it and is adamant it looks different. The spots are quite flat and rough, almost like spots of dry skin. But they've just sprung up out of nowhere

My DD has a rash like this Friday am. It took until Sunday am for it to look like the typical chicken pox blisters. But it’s now unmistakably chicken pox.

Just monitor him and hope for the best!

Oh
