So my granddaughter will be 2 in September and I don't hide my diapers as I'm disabled and everyone knows about them but I have always wandered if a young child such as my granddaughter understands the difference between adult diapers and children's diapers. Well this morning my granddaughter was soaked so I told her to go get me a diaper and to my surprise she went into my room opened the little nightstand and drought me one of my diapers lol I was so blown away thet she knew the difference. I told her she needs to get one of her diapers and she went over and grabbed one off the stack!. This has answered my question about do little children know the difference. Just thought I would share this with all of you.
