My house is cold, so I would keep the cheese.
As for the bacon, I would cook it, notice the smell is stronger than normal, then toss it. (I did this once when I found bacon that had come home from the shops and been left out for hours instead of finding its way to the fridge or freezer.)
If, when cooking, the bacon didn't emit a strong odour, I would eat some immediately, and if it tasted okay, offer some to the children, and cut up the remaining cooked pieces to put them in the freezer to use in meals later.
If my house was heated, I would just throw the bacon out, and be dubious about the cheese.
