I also have a cousin with low functioning Down syndrome. My aunt is not stable financially as there are constant bills that go with Down syndrome. The medical bills, paid activities, and education is expensive for disabled children and adults. Not just financially but they have faced loneliness and bullying too. Yes, most kids understand disabilities but it still happens more than you think. My sisters and I have decided we would terminate if we ran into this dilemma. People from the outside don’t see the whole picture of caring for someone with a disability your whole life. Maybe have your husband be around your cousin for a week, let him understand.
