If you're planning on adding another child to your family-or thinking about starting a family-you might want to consider getting the whooping cough vaccine before you get pregnant.
Why would you do that? According to a new study from Australia, babies who are born to women that are vaccinated with the whooping cough (also known as Pertussis) vaccine before they become pregnant have a 50% lower risk of developing the disease.
Whooping cough is an infection of the respiratory system. It mainly affects infants younger than 6 months old before they are immunized, and kids 11 to 18 years old whose immunity has started to decrease. Pertussis is characterized by severe coughing spells that may produce a whooping sound when the child breathes in.
It is highly contagious and before the Pertussis vaccine was available it killed 5,000 to 10,000 people in the U.S. each year. Now that there is a vaccine, the annual number of deaths is less than 30. But in recent years, the number of cases has started to rise. By 2004, the number of whooping cough cases spiked past 25,000, the highest level it's been since the 1950s.
The researchers looked at 217 babies ages 4 months and younger who had whooping cough. They compared them with 585 healthy infants born at the same time in the same area.
They discovered that a similar percentage of mothers - in both groups - received the whooping cough vaccine. However, 41 percent of the moms of healthy babies had been vaccinated at least four weeks before their infant became sick. However, of the mothers whose babies had whooping cough, only 27 percent of mothers had been vaccinated at least four weeks earlier.
Also in the healthy baby group, 26 percent of the mothers said they had been vaccinated before their baby was born, while only 14 percent of mothers whose babies had whooping cough said they had been vaccinated before delivery.

When your baby cries should you pick him or her up and walk or find a good rocking chair and rock back and forth? A new study from Japan says that infants respond best when mom (or any caregiver) picks them up and walks around.
Researchers said that the babies rapidly beating hearts also slowed down, proving that they felt calmer.
"Infants become calm and relaxed when they are carried by their mother said study researcher Dr. Kumi Kuroda, who investigates social behavior at the RIKEN Brain Science Institute in Saitama, Japan. Interestingly, the study also observed the same response in baby mice.
For the study, researchers monitored the responses of 12 healthy infants ages 1 month to 6 months. The scientists wanted to discover the most effective way for mothers to calm a crying baby over a 30-second period " simply holding the baby or carrying the infant while walking.
Results showed that infants carried by walking mothers were the most relaxed and soothed compared to babies whose mothers sat in a chair and held them. As a mother stood up with her cradled her baby and started to walk, scientists observed an automatic change in the baby's behavior.
These results held even after the researchers took into account other factors, such as the child's age and sex, and the mother's age and walking speed.
Kuroda said she was surprised by the strength of the calming effect. Researchers noted that the rhythm of walking might be more effective in soothing infants than any other rhythmic motion, including rocking.
Babies cry for a variety of reasons. If an infant is hungry or in pain, they'll most likely start crying again when they are laid back down. But sometimes a baby just feels a little anxious or unsure about their environment and will relax when held close and comforted. Kuroda acknowledged carrying might not completely stop the crying, but it may prevent parents from becoming frustrated by a crying infant.<
