How long do babies have maternal antibodies?
Maternal antibodies in humans decline over a period of 6 to 12 months (14–17). Since higher titers persist for a longer period of time, the kinetics of maternal antibody decline is correlated with the amount of maternal antibody present in the neonate after birth.

How do mothers pass antibodies to babies?
During the third trimester, antibodies are transferred from the mother to the fetus through the placenta (last 3 months of pregnancy). When the baby is born, this offers some protection. The type and quantity of antibodies a mother passes on to her unborn child depends on her own immunity.
