She just need prepregnancy counselling they will guide her in detail about everything...In most caesareans, a cut is made just along the top of your pubic hair. This is called a bikini cut. It usually heals by three months after your baby's birth. But waiting at least six months may be particularly important if you want to try for a vaginal birth next time. This is called a VBAC, which is a vaginal birth after caesarean section..

Hi,  it's best to wait atleast 18 months after a your caesarean section before becoming pregnant again. The longer your scar has to heal, the better, especially if you want a vaginal birth next time. A short gap can also increase the chance that you'll have problems with your placenta.
