Younger siblings, how to explain?

[Jo]

First off, I apologise for all the topics...Now that i've accepted that I could be trans, all I seem to want to do is ask questions (It's the scientist inside of me....)   -_-;

I was wondering if anyone had any experience with explaining being trans, especially explaining to younger siblings. With three little sisters (who are all minors), how could I possibly explain that their sister is actually their brother?
Do you think I should wait, and come out when they're a little older, so they will understand better, or is it better for them to know when they're younger?

[ I haven't come out to anyone beside on here, but I am planning to tell my mum sometime through the summer holidays. But this could change my mind on when I can come out, as I am really close to them and I would really hate to confuse them about this matter...]

Again, thank you everyone for taking your time to answer a newbie's questions, it's a massive help. I felt really amazing today, just knowing that someone else in the world understands how I feel

It's just the you inside you . Keep asking!

You know your sisters best. I would say, though, that keeping secrets in families makes people unhappy. But wait until you feel right about doing it, and don't think in terms of "protecting" anyone. There's nothing wrong about the thing you want them to know, after all.

i think you should try telling your sisters first. my own younger siblings have long since realized i'm not the "good girl" my mom always wanted me to be, so i'm sure that they wouldn't spare it second thought if i told them i'd rather be a guy. i'm even planning to use my sister's address to order a binder since i'm living with my parents and wouldn't want them to start asking questions before i've decided on my favorite place in the gender landscape (i'm probably more of an androgyne than ftm)

i think close siblings are more likely to accept you as "you", and not what they hoped for you to become. if they accept you, you'd have so much more support in dealing with your parents if any problems arise. and even if they don't accept you, you still have a chance of convincing them to keep it secret from your parents if you don't want them to know yet etc..
