Can newborns switch infant formula?

Generally, newborns can switch formulas, but the process should be done cautiously while observing the baby's adaptation. Each baby's gastrointestinal development varies, and certain ingredients may cause discomfort, such as spitting up or gas. When switching formulas, it is recommended to transition gradually by mixing the new and old formulas in proportion, allowing the baby's digestive system time to adapt to the new formula. A complete and immediate switch may lead to indigestion or allergic reactions, so it is important to closely monitor the baby's stool consistency, mental state, and whether there are abnormal symptoms such as rashes. If serious discomfort occurs, stop using the new formula immediately and consult a doctor for professional advice.

Start by preparing both formulas. On the first day, mainly use the original formula with a small amount of the new formula added in, and then gradually increase the proportion of the new formula each day until completely transitioning to the new brand. The entire process usually takes five to seven days. During this period, maintain regular feeding patterns and avoid interference from other foods. If a long-term switch is decided upon, choosing a formula suitable for the baby's age group and with a composition similar to the previous one is more advisable. Additionally, keeping a daily record of the baby's condition can help determine whether the new formula is suitable, ensuring the baby's healthy growth.
