I'm going to chime in as well (even though it looks like a lot of people have already)... learning to tandem feed was the best decision I ever made. I was losing my mind feeding on and then the other - especially during growth spurts where they both wanted to eat all the time. I mastered it by 2.5ish months - it definitely takes practice. I use the My Brest Friend double nursing pillow... when the girls were small, I would ease my fears of them falling off by wedging a receiving blanket behind each of them...
Looks great.... I have 16 mo old twins. The beginning is really rough, but there's some amazing payoff as they get older.
A few suggestions: - We had our girls crib together for the first 3 months or so. We kept one crib in our room and one in the nursery. During the day they would sleep in the nursery; at night they would sleep in our room so we could get to them faster and easier in the middle of the night.
Also, you may want to get one of these nursing pillows: http://www.amazon.com/My-Brest-Friend-Deluxe-Nursing/dp/B0032Z81M4/ref=sr_1_4?s=baby-products&ie=UTF8&qid=1426256362&sr=1-4
Good luck!!!
