number one, I hate the term stash. They aren't an illegal drug or a bunch of firearms. The FBI is not going to raid your house nor is DCF going to come take your kids away because they found some adult diapers in Dads closet. If your kids look in your closet they aren't going to fixate on your underwear or a bag of adult diapers. Remember, your the one who is into them........ they could care less. I keep my diapers on a shelf in the basement, in a storage room. They are not hidden but not out in the open, just with the rest of the toiletry supplies like toilet paper and paper towels. Granted I dont have printed diapers just plain white or blue ones in plain ordinary looking packages. Nothing kids would be interested in.
As for not wearing in front of them....... I dont know about you, but my kids have never asked me what color underwear I am wearing. Just put some pants on over your diaper and you will be fine. Don't wear just your diaper around the house. Put normal clothing on over your diaper...... and they wont notice.
When I go to bed I wear shorts or pajamas over my diaper so if I have to get up in the middle of the night or if one of my kids come into my bed its never a problem.
Just treat your diaper like underwear. You would not go modeling them to your children either.
This is what I am wearing tonight:
A nightingale adult diaper with my angry birds PJs over them. The PJs my kids got me for Christmas. You will not be able to see the diaper under the PJs.
