What to Prepare This Week

When Mom is 14 weeks pregnant with twins, it is a great time to start talking about names for your twins. Make a list of both boy and girl names and start this discussion early as it may take you a while to agree on two sets of names.

Dad’s Thoughts

By the time Mom reaches 14 weeks pregnant with twins, it is likely that you’ve known about the twins for several weeks. The shock is starting to wear off and reality is settling in. The twin pregnancy will be a stressful time for you and Mom. Take some time to consider how you can reduce the stress of the twin pregnancy to ensure a happy relationship with your wife and create an environment where you’ll have healthy twins.
