Hi Hilary, The game made it to the States -- my father called it skipping stones -- but I've never heard the name Dip Dap Do. I hope somebody can help you determine if it was a sweet name invented by your mother, or if perhaps its unique to the area she was from. My father was born here in Colorado. I don't know where he learned about skipping stones -- possibly from his mother, whose heritage was English. Norma Colorado, USA

We called it skipping stones in my part of Australia too, but my father was Welsh. Regards Jane
