Making sure you take care of yourself and your unborn child while you are pregnant, this can be by getting proper prenatal care and nutrition, as well as making sure you do not smoke cigarettes or use illegal drugs during your months of pregnancy, because whatever you intake your unborn baby will intake as well which will likely have a huge impact on them. Also, when you baby arrives; make sure you keep the air around your baby - at home, in the car and in all other environments which are free of smoke. However, if others insist on smoking then you should make sure they smoke outside, rather than inside your house to prevent your baby getting a whiff of the smoke.
