I work in a daycare. It's a chain of daycare centers staffed mostly by seasoned and educated professionals. I've been told by my boss and colleagues that we should change diapers regularly even if there is nothing in the diaper at all. For example, before a daytime nap or before a meal. I've been intending to ask them what their reasoning is, but I'm now doing some research online first.
My initial assumption prior to this advice was that there would be no reason to change the diaper unless there is urine or excrement in it. Or perhaps, unless it's hot and the child is very sweaty.
I guess my assumption may well be wrong, and therefore I'm asking this question.
I guess it could be something with comfort. Do diapers get less comfortable as they are worn, even if the child doesn't urinate or defecate? Or do they risk irritating the skin?
I'm primarily taking about disposable diapers, as cloth diapers are virtually never used in my part of the world.
I have searched the web for this question, and I have been unable to find anything that really answers the question.
