Wah, bagus la baby pertama dah normal delivery! Honestly, untuk yang kedua ni jangan stress sangat, some moms memang bertuah takde tear, tapi banyak yang tetap koyak sikit even dengan preparation, and it's totally okay jugak. A few of my mum friends yang successful (tear-free or minimal) mostly credit perineal massage dari 34 weeks onwards, pushing dengan slow dan controlled (ikut kata midwife, jangan force), and making sure you're relaxed during labour (easier said than done la kan!). Some swear by pelvic floor exercises throughout pregnancy, and one friend said practising squatting positions actually helped her body prepare better. That said, baby's size, position, and how fast labour progresses play besar jugak, so while these tips help, just go in dengan mindset siap untuk any outcome, because your safety and baby's safety comes first, okay? All the best for your second!
