Twin Baby Ultrasound
The presence of multiple fetuses is clearly apparent via ultrasound performed in the second trimester. Identifying gender is another matter, as twins or other multiples may position themselves in such a way that their genitals are obscured. Still, you have a good chance of learning your babies’ gender through ultrasound.
Besides being able to conclusively determine the exact number of fetuses, ultrasound is helpful in assessing the babies’ growth, placement of the placenta and any fetal anomalies.
Please note that many freestanding fetal imaging centers offering medical, reassurance or keepsake ultrasounds charge double for twins, because they’re looking at two babies. Others, however, may add a fixed amount (say, $50 to $75) to the base cost.
