hi, was in a similar situation for quite a while, one of the first things to look at is how often your parent's have you clean your room,if they really don't care, then it will be easier, but as akastus said, there is no guarantee of not being found. i hide my stuff in the winter side of my closet (live in Florida, need a jacket about two days every year.)in a large duffel bag, other options could include using a few banker boxes to box a bunch of old stuff, and sneak a box of diaper stuff in, i do this with paperwork. another thing to keep in mind is disposal, if you just wear them, disposal is as simple as a grocery bag that you throw in the trash just before it goes out, if you want to use them for their intended purpose, then you will want to get a box of one gallon zip lock bags (they don't have to be name brand, just buy some cheap ones) and individually bag each diaper, this will reduce the smell, also get an air freshener (the pop up ones work well)and stick it near your hiding spot for disposal. in the event you feel you may be discovered, have a large (preferably black) trash bag handy, if you need all of your stuff to vanish, stuff it in the bag and hide it in an area no one would suspect (i use a small patch of woods near my house, not too close, but not too far.). hope this helps.
