I do not think I reinvent myself. Wearing my hair differently or changing my style of dress is playing dress-up. I don't take it too seriously.
I think that for me, personally, a lot of my choices have been to do with my own issues of not feeling safe as a child and feeling a sense of stability.
Pregnancy was probably the best and the hardest thing I'll ever go through. I know for a lot of women, it can be wonderful and relatively easy.
