Silly Question

Okay, this may sound stupid. I've had 2 c-sections and I'm over 30. My sections were over 8 years apart, but we want another. Because of minor issues, I know I will have to have another section if we have another baby. Our youngest (and last surgery ago) is almost a year.

How long does your doctor say to wait between surgeries? How old should your baby be before you begin trying for another?

I've heard 18 months, 2 years, 3...

again, this is just concerning c-section babies.
