In reading your post, I would only worry about the 4 year old. The others are old enough to understand that in life there will be hard times and this year there will not be any presents. As long as there is food on the table, they will be okay. Of all my 4 kids the only one who will be getting a present is the 11 year old, and thank God he only wants sketch books, crayons and pencil grippers. Explain to them that this Christmas you do not have it, but when you get some money, they will get the presents they want. That is how we deal with our kids growing up. When we had it they would get what they wanted, but when we where short of cash, we would explain the circumstances and they would understand.
