This is so very sad. I have a severely disabled son. And while my husband and I do our very best to make sure his needs are met, to teach him as best he is able, to help him be happy, and know that he is loved-we also try our best to make sure our other children do not bear the burden of his care and miss out on life's experiences. They are involved in his care and such have learned a great deal of compassion. And sure, things like hiking or other activities our son simply cannot do are there but then, if needed my husband and I take turns, divide and conquer, wait at the finish line to celebrate to together or whatever else needs to be done to best accomodate all of our family member's needs. I absolutely support the bride in this scenario and am sad that her parents have created such a situation.
