National Sibling Day is a day to appreciate and cherish your brothers and sisters. Siblings are truly a special blessing that we probably all too often take for granted. They are often our best friends and supporters through life. Another reason to celebrate is that not everyone is lucky enough to have siblings.
The bond between siblings is extra-special, even more so if one of them has a life-long illness or a disability. Sibling Day is a way of honouring that special bond. Siblings Day was created by Claudia Evart, a freelance paralegal from Manhattan, NY. Evart started the day after losing both her sister at an early age. It is a day of celebration and recognition for brothers and sisters around the world.
