Q. Re – Last question. (How do you arrange a minimal seder for an elderly lady that is mentally OK, but bed ridden at home). What is the minimal Haggada reading that has to be said for her? Does she have to ask the four kashios?  Do you need a full seder plate to be brought to her room?
A. Horav Shlomo Miller’s Shlit’a opinion is that she does not have to ask the kashios, but she should listen to them in a language she understands. Then the answer should include the paragraphs of Avadim Hayinu, Mitchila, Vehi Sheamdah, the three paragraphs of Pesach, Matza and Maror, and Halel.
It is commendable to bring a convenient seder plate to her room if possible.
