If you are nearing the end of a pregnancy with twins, you may be interested in learning more about the babies. While your doctor should be able to keep a watchful eye on you and your children during you regular OBGYN appointments, you may want to have an elective ultrasound for more information. If you are having twins, here are four things to ask during a 4D ultrasound imaging service that can help you learn more about the babies and other things you may need to know for after the birth. 

How big are each of the twins?

There are times when one twin will be much larger in weight than another twin. While this is a problem that twin pregnancies can have, it may lead your doctor to wanting you to deliver sooner, rather than waiting around. During the ultrasound, you and your technician will be able to see the size of both of the babies. If the size of one or both of the twins is of concern, this is information that your doctor can use to tell you when you should give birth. 

Are the twins fraternal or identical?

If you are having twins, there is a chance that they could be fraternal twins or identical twins. If you are not sure which sort your twins fall under, a 4D ultrasound image can give you this information. Identical twins will share a single placenta while fraternal twins will each have their own placenta. This can be good information to provide to your twins and their doctors later in the event that a twin needs medical aid later on. Identical twins will have the same blood type and genetic makeup, while fraternal twins can have different blood types and differences in genetic makeup. 

What position are the babies in?

As you are nearing your pregnancy, it is a good idea to check and see what position your twins are sitting in. This can determine if you will be able to give birth vaginally or if it will be medically necessary to have a cesarean. If both of the babies have their heads facing the birth canal, they may be in prime condition to go through natural birth without issue. If one of both twins are breech or not getting in position for natural birth, scheduling a cesarean will be something that you and your doctor will need to arrange.
