My daughter did that, and someone told me that is a son of needed to potty train, I tried that but she really wasnt ready, so I switched to pull ups, or if she did have a diaper on, I would put her in one piece outfits, but when she was in the crib playing, I would take everything out of the crib, and just let her take her diaper off, I of course had a plastic cover under the sheet, that way if she did have a accident, all I had to do was take off the sheet, spray the plastic cover and wipe. She had a awful time with rashes, so I thinks thats why I did it, also at that time I switched to something called butt paste and it worked wonders.
