I *think* the huggies overnight diapers is the culprit of my son's rash in the waist/groin area.... I can't think of anything else... He never had a rash in the waist area with his daytime diapers (huggies little movers)...

Would you 1) put him in his daytime diapers for nighttime (and just deal with any leaks) or 2) use a different brand for overnights?
