Abstract: An infant nutritional device for delivering pre-measured micro dosages of essential multivitamin and mineral (MVM) to supplement infant diets particularly for those infants who are risk of malnutrition. The pre-measured micro dosages of MVM are presented in a cartridge that inserts into a housing of the nutritional device. The cartridge is in fluid communication with a nipple disposed in the housing. At least one seal of the cartridge is pierced and in fluid communication with a channel in the nipple, creating an air-tight seal, minimizing any air bubbles created during sucking by an infant. The MVM is in liquid form and contains at least one fat-soluble vitamin. The infant nutritional device eliminates the worry about inaccurate measuring, loss of material through spilling and overdosing or underdosing.
