It is common for babies to drop into the pelvis in preparation for birth around 37-40 weeks of pregnancy. However, every pregnancy is different, and some babies may not drop until labor begins. If your baby hasn't dropped by 38 weeks, there are a few things you can try to encourage the process. Walking regularly can help gravity assist the baby in descending into the pelvis. You can also try pelvic tilts or exercises that open up your hips. Additionally, maintaining good posture and avoiding slouching can create more space for the baby to move down. However, it's important to note that dropping does not necessarily indicate imminent labor, so there's no need to panic if your baby hasn't dropped yet. If you have any concerns or questions, it's always best to consult with your healthcare provider who can provide personalized advice based on your specific situation.
