I've never knowingly been "caught" diapered or had my diaperes (and being ab my baby stuff) uncovered.
And I'll be honest, for one reason or another I've been getting more and more "adventurous" with them over the past month. I still don't want people to actively know though. Just sort of an experiment, to see if I should be so afraid of being found.
Anyway, If anything what I've come to realize is that while we have no idea what to say neither do they, or how to react, or even if they should. And even if they do, if they are that close (family) they dont want to risk bringing up such an insignificant item (in the grand scheme of their lives) that may cause upset or whatever else to you.
With diapers and baby stuff I've come to just go with the flow.
A whole "what are you really going to do?" attitude, it wouldn't work for everyone though and its not to say I don't go out of my way to hide my stuff and I'm not exactly going to roam the streets in a onesie. Still as careful, just less concerned.
But its helped me be more relaxed and less tense around my lifestyle.
Take my post with a little salt.
