Raising a child with disabilities is like living in a yard with an invisible fence.

The trouble with an invisible fence is that you only learn where the perimeter is when you make the mistake of crossing the unseen barrier and get zapped by life telling you that you aren't allowed to go there.

Maybe it's a place like a preschool that doesn't want your child. Maybe it's a friendship that fades away as your lives take different paths. Maybe it's an expectation - like how holidays will look or what activities your family is going to participate in.
