PROBLEM DEFINITION

It is common that children in many households don’t like to wash hands and it is a challenge for  parents to lead their children to wash hands properly and help them foster the good habit of washing hands regularly. 

Parents

“My kids touch different things all the time. And some of those things can be dirty. We might not manage to prevent them from doing this each time. And sometimes they refuse to wash hands strongly.”

• Have not enough time to supervise their kids
• Being afraid of that kids can get sick easily
•It’s hard and time-consuming to lead kids how to wash hands properly.

Teachers

“We do lead the kids to wash hands in our courses, and we also ask them to wash hands after some activities. But sometimes, I actually don’t know if every kid does have washed their hands during the washing session.”

• It’s impossible to cover every kid
• It’s difficult to check if kids’ hands are actually clean
• Heavy workload.

Children

“I hate washing hands! it’s not fun at all. I want to play toys and smartphones. I feel very unhappy when mom asks me to wash hands.”

• Don’t like washing hands
• No interest
• Washing hands is no matter with fun.
