Here are some important guidelines for coloring Easter eggs with a three-year-old:
#1 - Be sure the child is covered from head to toe in something that protects their clothing. They have a way of getting stuff everywhere.
#2 - Make sure the adult who is supervising the child is covered from head to toe in something that protects their clothing. They have a way of getting stuff everywhere.
#3 - Use only hard-boiled eggs for this project. Raw eggs create a real mess, especially when handled by a three-year-old being supervised by her grandpa.
#4 - For extra safety, ensure that someone is supervising the adult who is supervising the child. That way, you have a responsible adult to clean up the mess.
If you are lucky, you will end up with beautifully-colored eggs like these AND a clean kitchen.
