Alhamdulillah, bagus la uri normal kali ni! A few of my mum friends did VBAC after their first caesar, and honestly preparation memang help, especially pelvic floor exercises dari week 28-30 onwards (squats, walking, kegel exercises memang recommended), and jangan lupa eat well dengan lots of fiber dan hydrate banyak-banyak sebab lahir normal kena kuat sikit. Some of them swear by dates (dari week 36), prenatal massages, dan staying active je, tapi yang paling important tu mindset positive dan komunikasi baik dengan OB sebab support system sangat perlu for VBAC success lah. Since your first was for placental position, do check in detail with your doctor about what they want to monitor this time around, and maybe discuss your birth plan early so everyone on the same page, all the best, mama!
