These plans vary in length based on age and are customized specifically for YOUR twins' needs. Newborn Twins Plan is to teach you how to transition your babies' into healthy sleep patterns early on and help you avoid the sleep issues that can set in as your babies grows.  Waking up to feed during the night is expected, very important and encouraged until babies are ready to drop the feeds.  Infant and Toddler Plans are to help your child fall asleep independently for night sleep and naps as well as getting them to sleep through the night.  Most babies sleep close to 12 hours a night, however all babies are different and yours may require a little less or a little more than 12 hours.  Some infants still require feeds during the night, and that is precisely what they will get with a customized plan.
