"Make the ideal feeding posture possible" - this is what the curve on Dr. Betta baby bottle is for. It was developed focusing on the difference in incidence of sicknesses for breastfed babies versus bottle-fed babies. All the pediatricians involved in our product development estimate that "70% of sicknesses that children experience in their first few years of life is caused by a lying-flat feeding posture". Our "Dr. Betta baby bottles" are developed for all the bottle-fed babies, so we sincerely hope to be your baby's choice.
