There are no official guidelines to assist in answering this question. I will search for relevant research papers instead.
From the Research
American Academy of Pediatrics (AAP) Recommendations
- The AAP recommends introducing complementary foods to infants at approximately 6 months of age 1
- There is no specific mention of blueberry consumption in the provided studies, but the AAP recommends introducing a variety of foods, including fruits, to infants and young children 2, 3, 1

- However, this study does not provide guidance on the introduction of blueberries to infants or young children, and its findings may not be directly applicable to this age group
Complementary Food Introduction
- The AAP recommends introducing complementary foods at approximately 6 months of age, but the optimal timing and order of introduction are still debated 3, 1
- A survey of pediatric practitioners found that most did not recommend waiting 3 days or longer between introducing new foods, unless the infant was at risk for food allergy development 3
