When introducing new food to infants, how often should it be done to monitor for allergies?

Introducing new foods to infants should be done once a day for a week primarily to monitor for any allergic reactions. This approach allows caregivers to carefully observe the infant for any signs of adverse reactions, such as rashes, digestive issues, or respiratory problems, following the introduction of each new food.

Having a single new food introduced daily gives enough time to isolate its effects, ensuring that if an allergic reaction occurs, it can be directly linked to the new food. Additionally, a week for observation provides a reasonable window to account for any delayed reactions that may not show up immediately.

This method of introduction not only helps in identifying potential allergies early on but also establishes a good pattern for diversifying the infant's diet over time.
