Germs are everywhere and it’s a good idea to encourage young children to develop good handwashing and hygiene habits early.
Here are some fun books that will get kids of all ages inspired (and knowledgeable) about germs and healthy hygiene so that it becomes a daily habit. My 7yo still has trouble ‘remembering’ to flush the toilet and wash his hands!
Finally, here’s an informative message from Sesame Street! It shows the steps that kids can take to keep healthy, with the help of Elmo and his mummy.
