Why Is My Baby Refusing Formula and Spitting Up? Pediatric Insights - Pediatrics

Share to:

The baby is not drinking milk and is also spitting up?


My younger brother is currently 2 months and 6 days old.
Is he refusing to drink milk? He was born weighing 3535g and measuring 51cm.
For the first few weeks after birth until he was one month old, he drank 150cc of formula (New Angel Baby formula) every four hours.
After his one-month vaccinations, he started to show signs of spitting up.
So, I switched him to 120cc every three hours.
After receiving the pentavalent vaccine on March 7, he began to refuse milk again, taking only about 30-60cc every four hours.
Sometimes he strains and spits up because he doesn't want to drink.
His activity level and spirit are good, so I'm really unsure of the cause.
Additionally, he has developed a strong preference for drinking water, but I'm worried that if he fills up on water, he will drink even less milk.
Therefore, I haven't given him water for the past few days.
Is this okay? Also, he has started to enjoy sucking on his hands.
Could you please advise me? Thank you.

Dr. Zhang Wenwang reply Pediatrics


Infants, like adults, have varying meal sizes.
Pay close attention to their activity levels and urine output.
If their height and weight are within the growth curve, there is no need to worry too much.

It sounds like you are experiencing some common concerns with your two-month-old baby regarding feeding and spitting up. Let's break down the issues you're facing and provide some insights based on pediatric knowledge.


Refusing Formula and Spitting Up
1. Refusal of Formula: It's not uncommon for infants to go through phases where they refuse to take formula or breast milk. This can happen for several reasons:
- Taste Preference: Babies can develop preferences for certain tastes. If your baby has been exposed to different flavors, such as from breast milk or even water, they might show a preference for those over formula.

- Discomfort: If your baby is experiencing any discomfort, such as gas or reflux, they may associate feeding with discomfort and refuse to eat. Spitting up can be a sign of gastroesophageal reflux (GER), which is common in infants.

- Developmental Changes: As babies grow, they become more aware of their surroundings and may become distracted during feeding times. This can lead to decreased intake.

2. Spitting Up: Spitting up is a normal occurrence in infants, especially in the first few months of life. Here are some points to consider:
- Normal Behavior: Many babies spit up after feeding, and this is usually not a cause for concern unless it is accompanied by other symptoms such as poor weight gain, excessive irritability, or blood in the spit-up.

- Feeding Techniques: Ensure that you are feeding your baby in a calm environment. After feeding, holding your baby upright for about 20-30 minutes can help reduce spitting up. Additionally, burping your baby during and after feeds can help release any trapped air that may contribute to spitting up.

- Volume and Frequency: You mentioned reducing the amount of formula to 120cc every three hours. This is a reasonable adjustment if your baby is spitting up frequently. However, if your baby is consistently taking less than what is recommended for their age, it may be worth consulting your pediatrician.

3. Water Intake: While it's important to keep your baby hydrated, infants under six months typically get all the hydration they need from breast milk or formula. Introducing water too early can fill them up and reduce their appetite for milk, which is not ideal for their nutritional needs. It's generally recommended to avoid giving water to infants under six months unless advised by a healthcare provider.

4. Hand-Sucking: Sucking on hands is a normal behavior for infants. It can be a self-soothing mechanism and is often seen as a sign of exploration and comfort. If your baby is sucking their hands, it may indicate hunger or a need for comfort.

Recommendations
- Monitor Feeding Patterns: Keep track of how much your baby is eating and any patterns in their feeding behavior. If you notice significant changes or if your baby is not gaining weight appropriately, consult your pediatrician.

- Consult a Pediatrician: Given the changes in your baby's feeding habits and the spitting up, it would be beneficial to discuss these concerns with your pediatrician. They can assess your baby's growth, feeding techniques, and overall health to provide tailored advice.

- Create a Calm Feeding Environment: Try to minimize distractions during feeding times and ensure your baby is comfortable. This can help improve their willingness to feed.

- Gradual Introduction of Foods: As your baby approaches six months, you can start introducing solid foods, which may help diversify their diet and encourage better feeding habits.

In summary, while it can be concerning when a baby refuses formula and experiences spitting up, these behaviors are often part of normal development. However, close monitoring and communication with your pediatrician will ensure that your baby is healthy and thriving.
