I just got a compliment from a 2.5-year old. 

My wife was playing with our son the other day, flipping through photos on her phone, seeing if he could name the family members (he could). She then came upon a shot she took of me, dressed as woman, from a recent night out.

We'd been talking about how to gently introduce our kids to my other identity, and I guess she felt brave enough to try it. So she shows our son the pic, and asks "Who's this, do you recognize this person?" I put my face next to the phone, hoping he'd catch on.

He looks kinda confused, does a double take at both of us, pokes his finger at the phone and says:
"Iz a girl!"

That pretty much made my day. I told him, "That's daddy!". He was kinda confused and didn't really react. Baby steps.
I guess there's some hope of looking feminine after all.

P.S.: He also really digs my nails every time I paint them. 

That is so cute! I just bet it made your day! I am so glad you are being patient and slowly bringing him up to speed. It will make a huge difference in the future and generate understanding for those different. Congrats and well done!

That's totally cool

I agree, well done.
