Issues of personal cleanliness such as showering/bathing, brushing teeth, finger/toe-nail maintenance, shaving, etc.
Keeping our children hygienic starts from birth and continues through young adulthood. New parents may have never experienced a need to keep another person hygienic and will have questions about best practices. As children grow up from the infant stage, teaching them the skills to perform their own hygiene turns into questions of "how", "when", and "how to teach and maintain a regimen." As children progress into the pre-teen and teenage years, new hygienic tasks are added which will continue through adulthood and many children experience fears, embarrasment, or a general feeling of ineptness.
Each stage of growth provides new areas for new and experienced parents to seek the advice and wisdom of others to help their child(ren) develop strong lifelong hygeinic habits.
