I'm going to need a bigger filing cabinet if I need to keep all of the kids folders until they're adults. I'm going to need a bigger house 
It is up to you how much you keep but I would recommend going electronic and not just paper copies.
I do an andecodotal type note on my computer and will write down things like "DCB came in this morning with a cut on left hand, DCM said it was from falling down outside" Later I take a picture of the cut and add "picture taken"
