Should You Supplement Your Baby's Diet with Immunoglobulin for Appetite? - Pediatrics

When it comes to supplementing a baby's diet, especially in the context of decreased appetite and elevated IgE levels, it is essential to approach the situation with caution and informed guidance. Your baby, being just over three months old, is still in a critical stage of development where nutrition plays a vital role in their growth and immune system development.

Firstly, regarding the use of immunoglobulin supplements, such as the one you mentioned (森永免疫球蛋白), it is important to note that while some parents may find anecdotal success stories, the scientific evidence supporting the routine use of immunoglobulin supplements in infants is limited. Immunoglobulins are proteins that play a crucial role in the immune response, but they are not a substitute for a balanced diet. In most cases, if your baby is consuming an appropriate formula (like HA1, which is a hypoallergenic formula), they should be receiving adequate nutrition without the need for additional supplements.
The decrease in appetite you are observing could be due to various factors, including growth spurts, teething, or even mild illnesses. It is not uncommon for infants to have fluctuations in their feeding patterns. If your baby is otherwise healthy, gaining weight appropriately, and meeting developmental milestones, this temporary decrease in appetite may not be a cause for concern. However, if the lack of appetite persists or is accompanied by other symptoms (like lethargy, vomiting, or diarrhea), it is crucial to consult your pediatrician.

As for introducing solid foods, the general recommendation is to wait until around six months of age before introducing complementary foods. However, if your baby is not showing signs of allergies and is developmentally ready, you may consider introducing rice cereal (米精) around four months. This should be done cautiously, starting with small amounts and observing for any allergic reactions. Given your baby's elevated IgE levels, it is particularly important to monitor for any signs of food allergies when introducing new foods.

In summary, while it may be tempting to supplement your baby's diet with immunoglobulin or other nutritional products, it is best to consult with your pediatrician or a pediatric nutritionist first. They can provide tailored advice based on your baby's specific health needs and family history of allergies. Maintaining a balanced diet, monitoring your baby's growth, and ensuring they are comfortable and healthy are the most important aspects of their nutrition at this stage.
