Disclaimer: Kids, .......DO NOT EAT SAND either. I warned you.....
My oldest kid, Jasmine, did it once.... It did not go very well.......but she got better and today she doesn't eat dirt or sand anymore as far as I know.
This is a wink towards my husband's mother.in-law, Maja Liäs. She is the one that used to say that an apple is like a stone in your stomach if you eat it before bedtime. That is what this one is based on. I hope you get the joke....
