Coming out to younger siblings

[Madeline]

My mum has decided that I need to come out to my siblings and at least one grandparent before I can see a therapist. In addition I recently cross dressed for the first time and would love to do it more but to do so I would have to come out to my siblings. My brother is 12 and my sister is 9. Does anybody have advice on how to come out to them and should I come out to them separately or together? Any experience would be super helpful!
Thanks!
Lots of love,
Maria!

Can't comment from a younger person point of view but when I let my family know I just called them one at a time and opened up to them. Everyone was great about it including my stepsisters.
My youngest brother is ok with it but is uncomfortable talking about it as he now has a big sister.
