PATIENCE !!
Under your current circumstances, settle the questions in your mind with a definite "I AM A DIAPER LOVER"
you don't have money or opportunities to experiment much with other things at present, and every item you add
to your stash is another item that may be found by a family member.
Once you are found out, caught, discovered........ you can't put the Geni back in the bottle.
Wait and be happy with what you have.
