So far for pregnancy I have tried a fetal carrier that I put on the minifig's back but this limits her movements. Specifically she can't bend too far in either direction and also she can't lay down the way she normally would (she would have to like bend her legs when she lays down or something to keep the fetus inside).
My minifigs don't have a hole in the belly where I can put a big white dome to illustrate pregnancy.
So what is the best way to show pregnancy without a pregnancy dome?
