Is it normal to change bra in front of mother?

Your just confident with your body, that's all. Your mother is obviously someone you really trust and feel comfortable around.
Totally normal!

I do it as well. It's my mother, she gave birth to me and put baby powder on my butt when I was a baby. If you think about it, your mother has already seen you naked since you were born so I'm just like meh.

I do it. But I don't flash myself. I'll turn around or something.

in all honesty most women don't care. i mean it's not as if they're doing a strip show.

I did it in front of my mum my dad and my 4 bros it was just one of those things so dont worry about it.

Your mum has exactly the same bits you do. Totally normal.

Nothing wrong with it.

I've never done it, but it's totally normal for those who do.

Totally normal. I don't see my mum, my dad, my sister or her husband as sexual beings. Have been casually nude in front of all of them.(though of course never ALONE with her husband...i just don't mind if he's WITH her...)
