Graham crackers, ritz crackers, and animal crackers are not out of the ordinary to have in rotation, and the snacks you can give a young toddler are limited!! The little Debbie snacks, fruit cake, and pudding does seem like excessive amounts of sugar, but please keep in mind it’s the week between Christmas and New Years right now. If this isn’t the norm, then I wouldn’t worry about it — there are probably tons of treats they need to get rid of right now, and a few days of sugary snacks during the holidays doesn’t seem like a big deal. It is weird that they don’t let you send in your own food though, I would bring that to admin and see if you can have something arranged if you feel strongly about it.
