Yes, antibiotics ideally 4 hours before delivery but that is difficult to predict at best.
Hospital are likely to monitor the baby for signs of infection, heart rate, temperature, respiration and likely to be every 8 hours for 48 hours but you can check your hospital protocol.

In the absence of intervention, 1 to 2% of infants born to colonised mothers, develop early onset GBS infections. This is the same as saying that a baby born to a colonised mother has 25 times more risk of being infected. This is reduced by 90% if antibiotics are given.
Infected infants present with respiratory distress, apnea or signs of sepsis within 24 to 48 hours of birth.
Case fatality of babies born after 33 weeks is 2 to 3% though there may be long term impacts of requiring ventilation or treatment in NICU.
If there are clinical signs of infection, the baby would need to be hospitalized in neonatal care for blood work and initiation of antibiotic treatment and prompt treatment reduces the risk of complications and the prognosis is excellent.
Factors that increase risk: labour before 37 weeks, more than 12 hours between waters breaking and baby being born, young maternal age, black race, internal obstetric procedures (membrane sweep, induction methods which involve inserting something into the vagina, vaginal examination), fever during labour
Monitoring after birth: temperature, heart rate, respiratory rate 3 times a day for 48 hours then daily.
If no antibiotics are given, this is increased to every 4 hours for the first 24 hours and then every 8 hours for the next 24 hours and blood pressure is also taken.
