Heather needs to definately say something to Laura. She needs to explain to her what she is doing to herself and the baby on the way. Heather needs to tell her all the harmful effects alcohol, smoking, and not exercising is doing to the baby on the way. I beleive she should also support Laura. Having a baby is alot of stress and going through it alone probably is not a good idea. Heather should explain that she is there for her and will exercise with her or help get her help. She needs to see a doctor and have the doctor explain all the risks of smoking and drinking while being pregnant. Also, the doctor can give her a plan of exercise or vitamins that need to be taken throughout the pregnancy. She needs to be a good friend and her support system.
