Food for Angels and how to keep them out of it are sometimes a problem.
What we did was for our fridge and freezer my mom bought me some red tie down straps at Wall Mart for $4.00. They are big enough to wrap around the refridgerator and another one for the freezer. You have to pull the latch on the strap to loosen it and if I keep the lock to the straps by the back wall. Mandy and Angie can't reach them,, yet anyway.
Food storage: I have heard and was about to buy locks for my cabinets. I really didn't want to drill holes in my cabnets for the locks so we ended up getting a very big wooden cabinet and putting a lock on this, and putting our food that was in cardboard, junkfood, and the girls snacks in there. This was probobly one of the best things i have ever gotten. It has saved me alot in buying food that Mandy had gotten into and alot of headaches from trying to keep her out of the cupboard. I still put my canned food in the cupboard. Mandy doesn't mess with the cans only because I think she knows she can't open them.
And if keeping tuperware around your house is a problem,, and you keep finding it in the sandbox outside,, a cabinet with a lock on it is the ideal place to keep it.
