Wondering how to break the news about your second baby to your first child when the time comes? Pediatrician William Sears, M.D., suggests saying something like: "When moms and dads love each other, they sometimes decide to have a baby." Connecting the due date with a holiday, he adds, will also make things more concrete: "Your new brother or sister will be here in time for Thanksgiving!" But if your child is under 2 1/2, he suggests you wait until the third trimester.
Nutritionists recommend 300 extra calories a day if you're carrying twins--on top of the extra 300 calories you need during pregnancy. Keep in mind some should-haves on your shopping list: lots of fiber, found in whole grains and fruit, to ease constipation; calcium to help build your baby's bones; and extra iron, which you can get from lean meats and dark, leafy veggies, to prevent anemia.
