Yes, it is possible for a baby to change its position in the womb at 7 months of pregnancy. During the second trimester, babies have more space to move around and can often be seen turning or flipping inside the womb. This movement is known as "quickening" and is a normal part of fetal development. As your baby grows, you may feel them shifting positions frequently. It's important to note that every pregnancy is different, and some babies may be more active than others. If you have any concerns about your baby's movements or positioning, it's always best to consult with your healthcare provider for reassurance and guidance.
