Before bedtime, limit fluids at night and ensure that your child uses the bathroom right before bed to prevent bedwetting.
Proper Hygiene for Girls
For girls, teach them to wipe from front to back. Wiping front to back will keep bacteria from entering the vagina and reduce the likelihood of urinary tract infections.
Protection for Boys
For boys, make sure they begin wearing an athletic supporter or "cup" as soon as they are involved in any kind of activity that could lead to groin injury, such as playing sports (Read "Ask a Urologist: Athletic Cups and Supports," from UrologyHealth extra Spring 2014 for more information").
