It is very easy to verify the existence of twins in utero: ultrasound will show two fetuses! Also, blood levels of HCG (used to detect pregnancy) are also usually higher in multiple gestations. Depends on how far along she is. As for "echoing" heartbeats, I'm assuming he's just using a doppler for this. Yes, there can be an echo, but NOT at a different rate! However, sometimes mom's heartbeat can be heard at the same time, and is often slower than the baby's. If she's "hyper" like me, though, her heart rate (especially if she was just told she might have twins!) could be in the 120's range--which is also low-normal for fetuses. At any rate, I would advise her to talk w/her dr. about an ultrasound to clear up the situation. If she really is going to have twins, pretending it's "just an echo" isn't going to make it go away, and will delay her acceptance of and preparation for a challenging pregnancy. I, too, agree that breastfeeding twins (especially since she's nursed before, & has a bit of confidence & experience) is MUCH easier than bottlefeeding. You can't bottlefeed two babies at once, so feeding takes up twice the time. For those well-meaning friends & family who say they can "help" if she bottlefeeds, point out how they can help in so many other ways: burping, changing, rocking the babies, tending to the older kids, housework, cooking, cleaning, errands, etc. Breastfeeding is MUCH less taxing than these things!
