The smoke from secondhand smoking from someone's cigarette, cigar, pipe or other tobacco product can be dangerous for you and your baby. Being around secondhand smoke during pregnancy can cause your baby to be born with birth defects or birthweight.

Secondhand smoke is also dangerous for your baby after birth. These babies would be exposed and will be at risk for health problems such as the following:

• Asthma. It's an health condition which affects the body's airways and can cause breathing problems.

• Bronchitis. It's an inflammation in the bronchial tubes which carries air to and from your baby's lungs. It could cause coughing and shortness of breath.

• Ear infections

• Pneumonia. It's an infection which affects the lungs
