Hi J.,
I too have twins, however mine are almost five. Sleep was a big problem for us as well in part because there are two of them and someone was always waking. We split up into 5 hour shifts to ensure atleast that much sleep after they were on bottles but before that time it is on you if you are breastfeeding. Most books recommended developing a strong sleep routine which sometimes helped. We would give them a lavender bath, turn down the lights and listen to Norah Jones before bedtime and then put them down at the same time every night. As for their waking, we just schlogged through until they started sleeping better.
