You can plan but it really depends on ur next pregnancy. I had elective csect for my first and was hoping to go natural for my 2nd. Gap was 3 years. However unfortunately my 2nd is a big baby too (3.8kg) and I'm a small mama. Still not dilated at 39 weeks and I didn't want to risk any complications so eventually decided for another elective csect again. It really depends on individual pregnancy and ur gynae. I know of a mom who cld even do a vbac with a big baby of more than 4kg. But she really researched alot and prepared her body well.
I asked my gynae the same so he said every pregnancy is different.. I also hope that my current pregnancy I can dilate well to natural too 🙏🏻
