If she's being irresponsible like that when she's pregnant then maybe she shouldn't keep her baby anyways. Actions are everything and this seems to be the start of DFS being called on her in the future for being so careless.
But it's her body, her baby...and if she doesn't want to make sure her baby is 100% healthy by eating right & not drinking then so be it. Her choice, she'll regret it in the future. I've known alot of girls to drink & stuff while being pregnant and their babies came out fine, so far. But that still doesn't make it right.
Even if my doctor said I could drink wine while pregnant I still wouldn't do it, Just because that's how I am, and my baby's life and the way he/she grows up in the future is very important to me! =D
