Context: A glass child is a term used to describe the experience of being a sibling of a child with disabilities or significant illness. The term “glass child” isn’t meant to imply that these siblings are fragile, but rather that they may feel see-through or invisible, as their needs and struggles may go unrecognized or unaddressed. Some may even feel as though their parents “look right through them” as they focus their attention on the needs of their disabled child.
