Nutrition Tips for Underweight Infants: Boosting Growth and Immunity

Low birth weight in infants?

Hello, Dietitian.
I would like to ask you about my babies.
They were born as twins with a birth weight of less than 1900 grams.
Now, at eight months old, one weighs only 6 kg and the other 6.5 kg, with heights of 64 cm and 67 cm, respectively.
Since birth, they have experienced frequent projectile vomiting and constipation, with bowel movements only once every eight days, which has caused me a lot of concern.
Could you please provide some dietary recommendations to help increase their weight, height, and immunity? They may be allergic children, as both parents have allergic conditions, and I also have asthma.
What dietary considerations should I keep in mind for them? Thank you very much for taking the time to answer my questions.
I would greatly appreciate your help.
Wishing you peace and joy.

Based on your description, your baby's growth is below the 3rd percentile.
It is advisable to monitor the growth curve to see if there is a gradual increase, as the baby was born with a lower birth weight.
If the baby's height, weight, and head circumference are consistently increasing without stagnation, there should be less cause for concern.
Regarding allergies, there are many hypoallergenic formula options available on the market that you might consider, but these may need to be used from birth.
As for introducing solid foods, you can slowly add seafood, proteins, and peanuts.
Ensure that the environment is clean and fresh.

Constipation is an issue that needs to be addressed.
There are some supplements available that can aid digestion, such as B vitamins and probiotics; it would be best to consult a physician for recommendations.
In terms of diet, it is essential to provide fruits and vegetables and ensure adequate hydration.
You can also gently massage the baby's gastrointestinal tract to aid digestion.
If the baby has not had a bowel movement for several days, this should be resolved promptly.
Regular walks with the baby can stimulate appetite; a normal appetite and good digestion are crucial for healthy growth and development.

When it comes to helping underweight infants, especially those who were born prematurely or with low birth weight, there are several key strategies to consider for boosting their growth and immunity. Based on the information provided, your twins were born with low birth weights and are currently experiencing challenges with weight gain and digestion. Here are some nutrition tips and considerations to help support their growth and overall health.

1. Nutrient-Dense Foods
Since your twins are underweight, it’s essential to focus on nutrient-dense foods that provide more calories and essential nutrients in smaller volumes. This can include:
- Avocado: Rich in healthy fats and calories.

- Nut butters: If there are no allergy concerns, nut butters can be a great source of protein and healthy fats.

- Full-fat dairy products: If they are not allergic, yogurt and cheese can provide calories and calcium.

- Eggs: A great source of protein and healthy fats, eggs can be introduced if there are no allergies.

- Smoothies: Blending fruits with yogurt or milk can create a calorie-rich drink that is easier to consume.

2. Frequent, Small Meals
Instead of three large meals, try offering smaller, more frequent meals throughout the day. This can help prevent overwhelming them and encourage them to eat more.

3. Hydration
While hydration is important, be cautious about offering too much water or other liquids before meals, as this can fill their stomachs and reduce their appetite for nutrient-dense foods. Offer water after meals instead.

4. Monitor Allergies
Given your family history of allergies, it’s crucial to introduce new foods one at a time and monitor for any adverse reactions. If you suspect they may have food allergies, consult with a pediatrician or an allergist for guidance on testing and dietary management.

5. Consider Specialized Formulas
If they are not gaining weight adequately, consider using high-calorie formulas designed for infants with low birth weight or those who are underweight. These formulas provide more calories per ounce than standard formulas. Consult with your pediatrician about the best options.

6. Probiotics
Probiotics can help improve gut health and digestion, which may be beneficial given their history of reflux and constipation. Discuss with your pediatrician about incorporating a suitable probiotic supplement.

7. Encourage Physical Activity
While it may seem counterintuitive, encouraging gentle physical activity can stimulate appetite. Simple activities like tummy time, crawling, and playing can help.

8. Regular Monitoring
Regular check-ups with a pediatrician are essential to monitor their growth and development. Your pediatrician can provide tailored advice and may refer you to a pediatric nutritionist for specialized dietary plans.

9. Create a Positive Eating Environment
Make mealtime enjoyable and stress-free. Avoid pressuring them to eat, as this can create negative associations with food. Instead, create a relaxed atmosphere where they can explore different foods at their own pace.

10. Consult a Specialist
If you continue to have concerns about their growth or if they show signs of developmental delays, consider consulting a pediatric dietitian or a specialist in pediatric growth and nutrition. They can provide personalized strategies and support.

Conclusion
Supporting the growth and health of underweight infants requires a multifaceted approach that includes providing nutrient-dense foods, monitoring for allergies, and creating a positive eating environment. Regular consultations with healthcare professionals are crucial to ensure that your twins are on the right track for healthy growth and development. Remember, every child is unique, and what works for one may not work for another, so patience and persistence are key.
