It’s important to support young siblings! There are several ways to provide support to young siblings, especially Sibshops.
The Sibling Support Project describes Sibshops this way:
Sibshops are pedal-to-the-metal celebrations of the many contributions made by brothers and sisters of kids with disabilities.
Sibshops acknowledge that being the brother or sister of a person with disabilities is for some a good thing, others a not-so-good thing, and for many, somewhere in-between. They reflect a belief that brothers and sisters have much to offer one another — if they are given a chance.
Sibshops are peer gatherings that include open and lively conversations, recreational and educational activities which gives the siblings a chance to meet with other kids their age with similar family dynamics.
