You've done as much as you can seasalty and have nothing to feel bad about. Your SIL, by choice, doesn't work; nor does he involve himself in the day to day management of his family life. You and your DH, on the otherhand, have to work to keep an income coming into your household. Yet your daughter has somehow come to the conclusion that the responsibility to drop everything and rush to her aid is yours. It's not. She chose to marry a man who is useless. She chose to have a large family with him. These are their choices and their responsibilities. They'll manage.
