Breastfeed them together to save precious time. This works well during the first weeks. After this you may have to breastfeed them one at a time depending on their particular hunger patterns.
There are several different ways that you can position the babies in order to nurse them at the same time. One way is to place the babies in front of you with their legs overlapping, making an X across your lap. The other position is to place both babies in the clutch hold. You will need pillows at your side (and maybe one on your lap) and you will place the babies on the pillows with their legs going toward the back of the chair. Remember that if you are placing the babies in front of you, you must try to keep their whole bodies turned toward you, their chests against your chest. Their bodies must not be facing up. This is very important to avoid soreness and also to make sure that the babies are receiving enough milk.
Use lots of pillows. There are special pillows available that help in positioning twins, or you can make a nursing pillow yourself.
Alternate feeding each baby from both breasts. This evens out their particular needs and also gives them extra visual exercise.
Learn different positions to breastfeed. Learning to nurse while lying down may be a little tricky to learn the first few weeks, but is worth it for the added rest you will get.
Prepare "changing areas" in several different places in your home.
Don't give babies a daily bath. Just make sure the diaper area and their faces are cleaned every day.
