Well knowing and direct involvement are two very different things.
My family knows I wear at night, and although it has not been brought up by either of us I'm pretty sure at least my sister has noticed me wearing during the day as well.
As far as my "little" side goes, again I wear lots of cute, fun, childish clothes all the time. I have no problems saying something new is from the girls section. Being able to still fit in clothes from the girls section is more an accomplishment for women then anything else lol.
So even thou my family knows I wear diapers, sometimes dress childish, have a stuffie collection, coloring books and pretty sure my paci has been seen more then once. (I do not hide it, it sits on my pillow) and none of them (except one) actually know I have a "little" side.
In fact I'm pretty sure many of them don't even know what an AB/DL or a little is.
And I am pretty happy with the current status quo being able to pretty much openly be little without them knowing I am a little.
