How can you be sure your baby is going to be healthy?
You can't make sure your baby will be healthy. You can however eat well, exercise, don't smoke or drink or practice any other unhealthy habbits. Go to all of your prenatal care visits, discuss any problems/concerns with your doctor and take care of yourslef. If you do all of this, the only thing left to do is sit back, hope for the best and rest assured that you have done everything in your power to ensure the health of your baby.
