Hey Kelli
I have three kids. They do question me from time to time.
"Daddy why are you wearing a dress??? Dresses are for girls!"
I reply:
"Remember, I told you, daddy is a transgender girl, so yes, she wears dresses."
Usually followed with:
"Okay Daddy. I always love you"
And a BIG hug.
But... this could be tough if your kids don't know. I think if you plan on dressing at home you should plan on coming out to them.
But even so, if you just want to alleviate your dysphoria, some styles of women's jeans don't look all that different from men's. You could try those.
