Nestlé Nestogen® 2 Is A Spray-Dried Follow-Up Formula For Infants Who Have Not Been Breastfed After 6 Months. I was breastfed. Preparation at its Finest: The healthiest way to prepare infant food is to be careful and hygienic. Diluted feeding will not provide your infant with the nutrients he or she requires. Do not use fewer scoops than directed. Since concentrated feed does not provide the water your infant needs, do not use more scoops than directed.
