Why Does My 7-Month-Old Baby Keep Spitting Up Milk?

The baby is continuously vomiting curds?

I have been very troubled; my baby is 7 months old, but after drinking milk, about an hour later, he/she vomits a white solid substance that resembles tofu pudding.
Previously, when I switched to Kabeikou formula, this phenomenon decreased, but the stools remained watery.
Then I switched back to New Angel formula.
Although the stools improved, he/she started vomiting again.
Could this be a problem with the formula? What type should I switch to that would be better?

Hello! The lower esophageal sphincter of infants is not fully developed, which makes them prone to spitting up.
This can be diagnosed by a pediatrician to determine if there are any related issues.
Infants may have individual responses to commercially available infant formulas, so it is important to observe and document their reactions.
Occasional vomiting may be influenced by various other factors.
It is advisable for parents to monitor their baby for a while when switching formulas to understand how well the baby adapts to the new formula.
To all the hardworking mothers out there, your efforts to provide the best for your baby are commendable! Wishing your little one health and safety.

It's understandable to be concerned when your 7-month-old baby is spitting up milk frequently. This is a common issue among infants, and there are several factors that could contribute to this behavior. Let's explore some potential reasons and solutions.

Reasons for Spitting Up
1. Immature Digestive System: At 7 months, your baby's digestive system is still developing. Spitting up can occur because the lower esophageal sphincter (the muscle that keeps food in the stomach) is not fully developed yet. This can lead to milk coming back up after feeding.

2. Overfeeding: Babies have small stomachs, and if they consume more milk than their stomach can hold, they may spit up. It's important to pay attention to your baby's hunger cues and avoid forcing them to finish a bottle if they seem full.

3. Air Swallowing: If your baby is drinking too quickly or is not properly latched onto the bottle, they may swallow air along with the milk. This can lead to discomfort and spitting up. Ensure that your baby is in a comfortable position and that the bottle nipple is the right size for their age.

4. Food Sensitivities: Some babies may have sensitivities to certain ingredients in formula. If you suspect that the formula is causing the spitting up, it might be worth trying a different brand or type of formula, such as a hypoallergenic option. However, it's essential to consult with your pediatrician before making any changes.

5. Reflux: Gastroesophageal reflux (GER) is another possibility. This condition is relatively common in infants and can cause frequent spitting up. If your baby seems to be in discomfort, arches their back, or has trouble feeding, it may be worth discussing with your pediatrician.

Recommendations
1. Feeding Position: Hold your baby in a more upright position while feeding and for about 30 minutes afterward. This can help reduce the likelihood of spitting up.

2. Burping: Make sure to burp your baby during and after feedings. This can help release any trapped air in their stomach, reducing the chances of spitting up.

3. Smaller, More Frequent Feedings: Instead of larger feedings, try offering smaller amounts of milk more frequently. This can help prevent overfilling the stomach.

4. Monitor Formula Changes: Since you mentioned changing formulas, keep a close eye on how your baby reacts to each one. If you notice a significant difference in spitting up or stool consistency, consult your pediatrician for advice on the best formula for your baby.

5. Consult Your Pediatrician: If the spitting up persists or is accompanied by other symptoms such as poor weight gain, irritability, or blood in the stool, it's crucial to seek medical advice. Your pediatrician can evaluate your baby's overall health and may recommend further testing or a specific formula.

Conclusion
Spitting up is common in infants, especially around the 7-month mark. While it can be concerning, many babies outgrow this phase as their digestive systems mature. By adjusting feeding practices and consulting with your pediatrician, you can help manage this issue effectively. Remember, every baby is different, and what works for one may not work for another, so it's essential to find the right approach for your little one.
