Managing allergies and cough in infants can be a challenging task for parents, especially when there is a family history of allergic conditions. Here’s a comprehensive guide to help you navigate this situation effectively.


1. Introducing Solid Foods
When it comes to introducing solid foods to your eight-month-old daughter, it is essential to proceed with caution, especially given your family history of allergies. Hydrolyzed formulas, like the Nestlé HA2 you mentioned, are designed to reduce the risk of allergic reactions, but they are not entirely free from the possibility of allergies.
Adding New Foods:
- Timing: It is generally recommended to introduce new foods one at a time and wait about three to five days before introducing another. This allows you to monitor for any allergic reactions.

- Wheat and Barley: As for adding wheat (麦粉), it is advisable to introduce it after your child has successfully tolerated other grains like rice and oats. If there is a concern about wheat allergies, you might want to consult with a pediatrician or an allergist before introducing it.

- Bone Broth and Fish: Bone broth can be introduced around six months, while fish, such as the吻仔魚 (small fish), can typically be introduced around nine months, but always ensure that it is well-cooked and finely mashed to avoid choking hazards.


2. Coughing in Infants
Coughing in infants can be concerning, especially when it occurs without other symptoms.
Possible Causes:
- Allergies: Yes, infants can exhibit allergic reactions, and a cough could be a sign of allergic rhinitis or asthma. Allergies can manifest as coughing, sneezing, and nasal congestion.

- Environmental Factors: Consider environmental triggers such as dust, pet dander, or smoke. Maintaining a clean environment can help reduce exposure to allergens.

- Infections: Sometimes, a cough can be due to a mild viral infection, which is common in infants. If your daughter is otherwise healthy and active, it may not be a cause for immediate concern.

When to Seek Medical Attention:
- If the cough persists for more than a week, worsens, or is accompanied by other symptoms like fever, difficulty breathing, or wheezing, it is crucial to consult a pediatrician.


3. Calcium and Respiratory Health
There is some evidence suggesting that adequate calcium intake can support respiratory health, but it is not a standalone solution for preventing allergies. Calcium plays a role in various bodily functions, including muscle contraction and nerve signaling, which can indirectly support respiratory function.

Dietary Sources of Calcium:
- For infants, breast milk or formula is the primary source of nutrition, and they typically receive adequate calcium from these sources. Once solid foods are introduced, you can include:
- Dairy Products: Yogurt and cheese (if tolerated).

- Leafy Greens: Cooked spinach or kale can be introduced as purees.

- Fortified Foods: Some cereals and plant-based milks are fortified with calcium.


Conclusion
In summary, managing allergies and cough in infants requires careful monitoring and a proactive approach to introducing new foods. Given your family history of allergies, it is wise to consult with a pediatrician or an allergist for personalized advice. They can provide guidance on food introductions, potential allergy testing, and management strategies tailored to your daughter’s needs. Always prioritize a clean environment to minimize allergen exposure and seek medical attention if any concerning symptoms arise.
