Allergic Conditions in Infants: Key Concerns for Parents

Q: Allergic Conditions in Infants: Key Concerns for Parents

Hello Ms. K： 1. As you mentioned, the child may have atopic dermatitis. Generally, children with allergic tendencies are more prone to this condition. It is important to manage it through proper skincare. You can use baby soap for cleansing and then apply a

Allergic constitution

My son is currently 4 months old, and I would like to consult with the doctor regarding the following:
(1) When he was 3 months old, due to his allergic constitution, we switched from Mead Johnson Enfamil to Nestlé HA1.
Initially, he had two small patches of skin-colored alopecia on the outer side of his calves, but later, the rash gradually increased in number and spread to his face, hands, feet, and both sides of his abdomen.
It becomes red during humid weather or when he cries.
Under what circumstances do these rashes become itchy, and how long will they persist before disappearing?
(2) Will drinking Nestlé HA1 lead to calcium deficiency in the future, affecting his development? If we do not introduce solid foods and continue with this formula until he is 9 months old, how much improvement can we expect in his allergic constitution?
(3) He has had two colds in the past month.
Is this related to his allergic constitution? Do children with an allergic constitution generally have weaker immune systems?
(4) Nestlé HA1 has a bitter taste.
Can a 4-month-old infant perceive bitterness? Why has he recently reduced his intake from 150cc five times a day to only 110cc five times a day and refuses to drink more? We are starting to worry about his nutritional intake, but he still has regular bowel movements every day.
(5) Does he need to undergo blood testing for allergies?
(6) There are food additives containing Bifidobacterium available in the market.
Do they truly enhance gastrointestinal absorption? If he is primarily on Nestlé HA1 at 6 months old, is it appropriate to gradually introduce regular growth formula at that age?

Hello Ms.
K:
1.
As you mentioned, the child may have atopic dermatitis.
Generally, children with allergic tendencies are more prone to this condition.
It is important to manage it through proper skincare.
You can use baby soap for cleansing and then apply a moisturizer.
If there is no improvement, it is necessary to consult a physician for evaluation.
2.
The nutritional components of HA formula should not differ significantly from regular infant formula.
3.
The likelihood of illness in children increases after 4-6 months, as the maternal antibodies provided to the child gradually diminish around this age.
The child will need to build their own immunity over time.
4.
A child's appetite may not consistently increase.
As long as they are active, have normal bowel movements, do not exhibit unusual crying, and their weight is within the standard range, there is no need for excessive concern.
5.
For children under two years old, it is not advisable to conduct allergen testing too early due to their unstable constitution.
6.
The addition of Bifidobacterium is beneficial for children.
If the child is gradually growing, Nestlé HA2 can be used until they reach three years of age.

Understanding allergic conditions in infants is crucial for parents, especially when dealing with symptoms that can be distressing for both the child and the caregivers. Let's address your concerns one by one.

1. Skin Rashes and Allergic Reactions: The skin issues you describe, such as the patches of skin that have lost color and the subsequent spread of rashes to other areas, could be indicative of an allergic reaction or a condition like eczema, which is common in infants with allergic tendencies. These rashes can become more pronounced during periods of heat or stress (like crying), as increased blood flow can exacerbate redness. The duration of these rashes can vary; they may persist for weeks to months, but with proper management, including moisturizing and avoiding known irritants, they can improve. If the rashes are itchy, it’s essential to consult a pediatric dermatologist for appropriate treatment options.

2. Nutritional Concerns with Formula: Nestlé HA1 is a hypoallergenic formula designed for infants with a predisposition to allergies. While it is formulated to be gentle on the stomach, it is essential to ensure that your child receives adequate nutrition. If you are concerned about calcium deficiency, it’s worth noting that most hypoallergenic formulas are fortified with essential nutrients, including calcium. However, introducing solid foods around six months can help diversify your child's diet and improve nutritional intake. The impact of prolonged formula feeding on allergic conditions is still debated, but early introduction of allergenic foods (under guidance from a pediatrician) may help reduce the risk of developing allergies.

3. Frequent Colds and Allergic Conditions: It is not uncommon for infants with allergic tendencies to experience more frequent respiratory infections. Allergies can lead to inflammation in the airways, which may make them more susceptible to infections. However, this does not necessarily mean that your child has a weaker immune system; rather, it may be a response to environmental allergens. Maintaining a clean environment and minimizing exposure to allergens can help improve your child's overall health.

4. Taste Sensitivity in Infants: Infants can indeed detect different tastes, including bitterness. If your child is refusing to drink the formula, it could be due to the taste or a natural developmental phase where they are becoming more selective. It’s crucial to monitor their intake and ensure they are getting enough nutrition. If they are still having regular bowel movements and appear healthy, it may just be a phase. However, if you are concerned about their nutritional status, consulting with a pediatrician is advisable.

5. Allergy Testing: Blood tests for allergies can be helpful in identifying specific allergens that may be affecting your child. However, these tests are usually recommended when there is a clear history of allergic reactions or if the symptoms are persistent and concerning. A pediatric allergist can provide guidance on whether testing is appropriate for your child.

6. Probiotics and Digestive Health: Probiotics, such as those containing Bifidobacterium, may help improve gut health and enhance nutrient absorption. However, the evidence supporting their use in preventing allergies is still emerging. Introducing a regular formula at six months, alongside Nestlé HA1, can be a good strategy, but it’s essential to do this under the guidance of your pediatrician to ensure it aligns with your child's specific health needs.

In summary, managing allergic conditions in infants requires a comprehensive approach that includes monitoring symptoms, ensuring adequate nutrition, and consulting healthcare professionals when necessary. Regular check-ups with your pediatrician can help track your child's growth and development while addressing any concerns about allergies or nutritional needs.
