I know what you mean ;-). My little rascals love a larger sandy corner in our garden. The kids don't care that the adults would prefer it neat ;-). You can imagine that our floor is all crunchy most of the time ;-). Have a great day - maks :-)
My MonkeyMan came into the house yesterday with his hiney covered because he "fell" into the mud. He loves makes dams and such in the backyard.
My 2 little ones have a mud pie maker - its great lol
