We began using Similac NeoSure because our son was born prematurely at 29 weeks due to my having severe eclampsia.  The Similac NeoSure has helped our 2lb 7oz. baby boy grow into a very healthy 17lbs at 7 months old.  He is very alert and doing very well considering his prematurity.  He has no issues with vision, physical ability, or respiration. At his physical therapy appointment, he rated in the eighty third percentile for his "adjusted age". (That is the age he would be if born at term). Also, this formula is very sensitive to the immature digestive tract so our son has had no trouble...
