During pregnancy:
If you already know you are a hepatitis B carrier, you should not receive any hepatitis B medication during your pregnancy. If you are already receiving antiviral medication, you should talk to your doctor about it.
At the time of delivery:
More than other newborns, your baby will need a shot of hepatitis B immunoglobulin at birth, in addition to the first dose of hepatitis B vaccine. The first dose of the hepatitis B vaccine and the hepatitis B immune globulin should be given within 12 hours of birth. This will prevent more than 95% of hepatitis B infections.

Caesarean section does not reduce the chance of the newborn contracting hepatitis B virus from the mother. The best way to stop the infection is to have the immunoglobulin shot (HBIG) and complete the three hepatitis B vaccinations on time.
Six months after delivery:
It is very important to complete the hepatitis B vaccination on time. 95% of newborns are thus protected from hepatitis B for life.
The hepatitis B virus is not transmitted to the newborn by feeding the mother’s milk, and you can definitely feed the mother’s milk. (Source: Sohu.com)
