Think back to what you learned in Study Session 10 about twin pregnancy.
What are the three signs of twin pregnancy?
The uterus grows faster or larger than normal. You can feel two heads or two bottoms when you feel the mother's belly. You can hear two heartbeats (this is not easy, but it may be possible in the last few months).
What are the two ways to try to hear the heartbeats of twins?
Find the heartbeat of one baby. Ask a helper to listen for other places where the heartbeat is easy to hear, and both of you tap the rhythm of the heartbeats.
Use a watch to help you count the two heartbeats.
