During labor, continuous monitoring of the mother and baby is carried out to ensure their safety and well-being. This includes monitoring the mother's vital signs, fetal heart rate, and progress of labor. 

The success of a VBAC depends on various factors, including the strength and integrity of the uterine scar from the previous C-section, the progress of labor, and the absence of any complications. If all goes well and the labor progresses without any complications or signs of distress, a vaginal delivery can be achieved.

However, it's important to note that VBAC is not suitable for every woman who has had a previous C-section. Some factors, such as certain medical conditions, previous uterine surgeries, or specific concerns about the safety of the mother or baby, may make a repeat C-section a more appropriate choice.

The decision to attempt a VBAC should be made in consultation with your obstetrician and gynaecologist who can evaluate individual circumstances and provide guidance based on the specific risks and benefits. The ultimate goal is to ensure the safest and most appropriate delivery option for both the mother and the baby.
