Unexpected Expenses

We're working on our budget. After this week, I'm thinking that the unexpected expenses category needs to be MUCH larger. Earlier, I wasn't thinking of things like:

$15 to dry clean our bed skirt of vomit
$150 (or more!) to replace the cd player stolen from our van
$15 to replace the science cd that was IN the cd player that was stolen from the van
$60 for supplies to create a patio (using stones that were given to us)
$20 for salad and other perishable ingredients purchased for our party tonight (which was cancelled due to sick children)
$10 to purchase a new garage sale toy for Tate to walk behind after his breaks
$5 for replacement cleaning supplies after the boys clean the bathroom
$5 for more paper towels, too
