smoking while pregnant

Belinda
I never understood why women who smoke while they are pregnant, look at it as if it's a game. 
I mean it might not be all ladies who think of it that way. But my sister has a friend who smokes and we're not to far behind eachother. But, my sister my mom and her always find places for her to hid to smoke her cigs. 
I'm just like, if it's a habit you have to hid from them why do it. 
But, it frustrates me to no end, because I've seen what cigs do to babies. Both my sisters children have asthema along with stomach issues and everything else. 
Along with every other baby I've come in contact with whose mother smoked with them.
I'm just like when will you stop being selfish. And realize. The body you have inside of you, isn't yours. Your just the vessel until that body can survive.
