Kids will get dirty. Babies will get very dirty.
Dirt will not kill your children. You, however, after 8 days camping and no shower, might. Or at least try and lose the dogs in the woods.
Two year olds will quit napping, one year olds will wake up before dawn and teenagers will want to stay up until midnight. And you will decide that Jesus Himself made the water into wine and you will support that miracle in anyway possible.
And then you will come home and have to do laundry for a week. And take a very, very long shower.
