Hello, Janette. You ask for research about alternating sides. I don't have references, but you should be able to find them under amblyopia ("lazy eye"). Years ago, there was research that showed that lazy eye occurred primarily in bottle-fed babies. The thinking was that only the baby's eye that is farthest from the mom's/caregiver's body had the chance to practice focusing well because the eye that was next to the adult's body was too close to allow focusing. Lazy eye very rarely occurs in breastfed babies, most likely because they usually feed from both breasts (whether at the same feeding or at alternating feedings throughout the day) so both eyes get equal opportunity to be the "outside" eye which can focus. I always wondered if the few breastfed babies who did develop this condition were: a twin who always nursed from his "assigned" breast; a baby who preferred one breast to the point where mom gave up trying to get him to take the other one; a mother who had only one breast that worked well (cancer, lack of ductal development, etc.).
