Is it true first baby if c section, second baby can't try normal birth?

It might be yes and no. every pregnancy has different condition, it's better to discuss your condition with the expert. There are some condition that must be considered such as the distance between first and second pregnancy, the condition of first c section, the thickness of skin in c section area and etc. Some mommies can do the normal birth in the 2nd pregnancy, but some mommies can't do it.

VBAC is now normal and there are many gynaes who are pro normal even aft csect. I had elective csect for my first and a successful normal delivery 2.5 years later. U wld be advised to wait at least 1-2 yrs before getting pregnant again to reduce risk of complications.
