Seriously, this could happen. Now I know what you are thinking, there is no way a mother would let her child eat off the floor, right? But I'm warning you, it is not that far off base.
Now I'm not saying that it has happened to me. But it could happen to someone.
Hypothetical situation: A mischievous, crawling baby, who has been a royal terror for most of the evening, finds a bag of Ritz crackers in his diaper bag, and starts to bang them around on the floor until there is not one whole cracker left in the bag. Perhaps this cheap, non "Ziploc" brand bag then opens with crumbs flinging all over the living room tile. Let's just say that at this point the mother is probably exhausted, and just thankful for the opportunity to have five minutes to sit and eat a cup of minestrone soup. She probably would just allowed the mischievous child to enjoy the treats he has now produced, within reach, all over the floor.
Mama and Baby are both happy.
