  The formula must contain DHA and ARA. These are crucial fatty acids that support brain and eye development.

• Carbohydrates

  The main carbohydrate in most infant formulas is lactose. Some formulas have alternative carbohydrates for babies with lactose intolerance.

• Caloric Content

  Choose a formula with a caloric content that meets the baby's needs. Usually, the recommendation is 20 calories per ounce.

• Special Dietary Needs

  Seek formulas that cater to special needs if the baby has specific dietary requirements. This includes metabolic disorders and gluten intolerance.

• Preparation and Convenience

  Think about the formula's preparation type. Options include ready-to-use liquid, powdered form, and concentrated liquid. Ready-to-use liquid formula is the most convenient but costly. Concentrated liquids need mixing with water. Powdered formula is the most affordable but requires accurate measuring and mixing.

• Environmental Considerations

  Those worried about the environment can consider organic formulas. These come with ingredients that are free from pesticides and synthetic fertilizers.

• Brand Reputation and Recommendations

  Choose formulas from reputable brands. Also, read the recommendations of healthcare professionals and other parents.

Functions, features and design of milk chemical formula

Milk formulas come in various designs, each with distinct functions and features tailored to meet the diverse needs of infants and young children. Here are some common designs along with their functions and features:

• Standard Milk Formulas

  This is the most commonly used design for infants without specific dietary needs. It contains a balanced combination of proteins, fats, and carbohydrates that are similar to breast milk. The formula is fortified with essential vitamins and minerals. It is available in powder, liquid concentrate, and ready-to-use forms.

• Infant Milk Formula

  This is a design for infants from birth to 12 months. It is developed to closely mimic the composition of breast milk. Usually, it contains whey and casein proteins in a ratio similar to breast milk. This design has easy-to-digest proteins and fats, including DHA and ARA, which support brain development.

• Follow-On Milk Formula

  This is a design for older infants and young toddlers, usually from 6 to 12 months. It contains higher levels of iron to meet the increasing nutritional needs of growing children. The formula has a different protein and carbohydrate ratio compared to standard infant formulas.
