If you wean your baby from breastmilk prior to their 1st birthday , you will need to give iron-fortified baby formula. Cow’s milk and other milk’s based on plant foods, like rice, almond, soy, etc. are NOT a substitute for baby formula. (1) Ask your healthcare provider what they recommend if you have questions. These milks do not have the proper calorie density, protein quality and can contain an imbalance of other nutrients your baby needs to grow and thrive. When your baby is 1 year old, whole cow’s milk is recommended to provide enough fat and calories unless your doctor/healthcare provider gives you different information.
