It is common for babies to turn into a head-down position by the end of the third trimester, but some may take longer. If your baby has not turned by 7 months, there are a few things you can try to encourage them to move. Firstly, spend time on all fours or in positions that allow gravity to help shift the baby's position. Gentle exercises like pelvic tilts and swimming can also be beneficial. Additionally, consider seeking guidance from a healthcare provider or midwife who can provide specific techniques such as external cephalic version (ECV) or suggest alternative methods to help your baby turn. Remember that every pregnancy is different, and it's important to consult with a medical professional for personalized advice and support throughout this process.
