I've only had an large applix UD wrap, never tried it over my MEOS but despite the wrap being roomy in the bum I don't think it would be wide enough in the crotch area, I don't have the wrap anymore to try it for you though, hope someone else can be more helpful.
I have 3 upsy daisy wraps they are high cut in the leg so I don't think they will fit over your motherease and sandys as they have frilly type legs don't they? I use ours over our weenotions and dunk n fluff's Hope that helps,
I have used one as an emergency over a bedbug but it had to be pulled a lot at the front to get it to fit also had to put the wing velcro half way down the front part to stop the legs gaping. Haven't used it with anything else though
