For a single baby, it's usually around 36 weeks, but with my twins, it was a total space jam in there, haha! One was head down and the other was doing acrobatics. Don't stress too much about the exact week, they'll find their way.
It generally happens in the late third trimester, around 36 weeks, but please check with your gynac during your scans. Every pregnancy is different, and only your doctor can tell you the exact position safely. Don't try any exercises to force it without asking them.
It typically happens after 34-36 weeks as your body gently prepares for birth. I know how every little milestone feels so heavy when you've struggled to get here. Trust your body and your doctor, everything is moving in its own perfect time.
Usually it happens around 34 to 36 weeks, especially for first-time moms. My MIL used to make me do light household work and walk slowly so the baby drops easily. It really helped my baby's head engage on time!
For most women, it happens around 34-36 weeks, but don't worry if it's late. With my PCOS history, I was always anxious about every milestone being delayed, but my baby's head fixed around 37 weeks. Just stay patient and supportive of your body.
