It is not safe or recommended to add trans-fat-containing cooking oils to your infant daughter's formula mix. Trans fats, also known as partially hydrogenated oils, have been linked to an increased risk of heart disease and other health problems. Infants and young children are especially vulnerable to the negative effects of trans fats, so it is important to avoid them as much as possible.
Pediatricians generally recommend that infants be fed a diet that is high in essential fatty acids, such as omega-3 fatty acids, which are found in fish, flaxseed, and other foods. However, these are different from the trans fats found in partially hydrogenated oils and should not be confused.
Instead of adding oils to the formula, it's recommended to speak with your pediatrician about appropriate sources of essential fatty acids for your daughter. They may recommend a formula that is enriched with these nutrients or suggest other foods that can be introduced as your daughter begins to eat solid foods.
