Help a Grandfather Care for His Grandchildren

We're raising money for a grandfather who has taken on raising his grandchildren. All while he's the main breadwinner, his wife suddenly passed after making a visit to the hospital. So now he has to give fulltime attention to his special needs grandchildren, because his wife was caring for them day to day. Anything donated will go solely towards raising his 2 grandchildren and helping take of care expenses/bills to help raise them. So if you could donate anything to help in his time of need, it would greatly appreciated.
