Formula Feeding And Spit-Up: What's Normal For Newborns?

It's not uncommon for newborns to throw up formula, and it's usually not a cause for concern. However, it's important to distinguish between spitting up and vomiting, as they have different causes and implications. Spitting up is typically effortless and occurs when a baby is fed too much, swallowed too much air, or burped. On the other hand, vomiting is more forceful and can be caused by various factors such as milk protein allergy, infections, or gastroesophageal reflux disease (GERD). While most cases of newborn vomiting are harmless, it's important to monitor for any signs of dehydration or other concerning symptoms and consult a doctor if vomiting persists or is accompanied by other symptoms.

The difference between vomiting and spitting up

It is common for newborns to throw up formula, and it is usually not a cause for concern. Their new digestive systems are still learning how to process milk. However, frequent vomiting may indicate an underlying issue, and you should consult a doctor if this is the case.

Spitting up is a common occurrence in healthy infants, especially in their first year of life. It is relatively harmless and is usually the result of a still-developing digestive system or overfeeding. Spit-up is a gentle, painless flow of milk from the baby's mouth, often accompanied by a burp. It is sometimes called "regurgitation" or "gastroesophageal reflux". This happens when the milk comes back up from the stomach and into the mouth. Spit-up is usually not an issue, and most babies who spit up are "happy spitters", meaning they are content, comfortable, and growing well.

On the other hand, vomiting is more forceful and comes from deeper in the baby's stomach. It is a sign that the baby's stomach is rejecting the milk. You might see your baby strain and recoil before they projectile vomit. This force is due to the contraction of the stomach muscles. Vomiting may also make your baby look more uncomfortable. Additionally, vomit looks and smells different from spit-up because it is usually mixed with stomach juices.

If you are unsure whether your baby is vomiting or spitting up, look for other symptoms of vomiting, such as dehydration, weight loss, or unusual sleepiness or weakness.

How to tell if your baby is vomiting or spitting up

It's not uncommon for newborns to throw up formula, and it's usually not something to worry about. However, it's important to know the difference between spitting up and vomiting, as vomiting can sometimes indicate a more serious issue. Here are some ways to tell if your baby is vomiting or spitting up:

Spitting Up:

• Spitting up is common in healthy infants, especially during the first year of life.
• It is often the result of a developing digestive system or overfeeding.
• It is relatively harmless and usually resolves by the time the baby reaches 12 to 14 months of age.
• Spit-up is a gentle flow of food or milk from the baby's stomach to their mouth, sometimes called "reflux", "regurgitation", or "gastroesophageal reflux".
• It often occurs when the ring of muscles between the oesophagus and stomach, known as the lower oesophageal sphincter, doesn't tighten properly, allowing milk to come back up.
• It is usually not painful for the baby, and they may even smile during spit-up.
• Spit-up often occurs with a burp and can also happen when the baby swallows too much air.
• The amount of spit-up may look like a lot, but it's typically only 1-2 tablespoons at a time.

Vomiting:

• Vomiting is a forceful ejection of stomach contents, often accompanied by muscle contractions.
• It comes from deeper in the baby's stomach and is a sign that their stomach is rejecting the food.
• You may see your baby strain and recoil before they projectile vomit.
• Your baby might appear more uncomfortable during and after vomiting, and the vomit may look and smell different as it is mixed with stomach juices.
• Vomiting can be caused by various factors such as overfeeding, not burping properly, reflux, constipation, or a stomach bug.
• In rare cases, vomiting can be a sign of an allergy, digestive problem, or other medical condition.

If you're unsure whether your baby is vomiting or spitting up, look for other symptoms such as discomfort, fussiness, poor weight gain, or respiratory issues like choking, coughing, or wheezing. If you have any concerns, it's always best to consult your healthcare provider.

Reasons for vomiting, including milk protein allergy, infections, and reflux

Reasons for Vomiting Formula

It is common for newborns to throw up formula, and there are several reasons why this might happen. It's important to remember that vomiting is often normal and that newborns are still getting used to keeping milk down. Their digestive systems are new and still learning how to process milk. However, if your baby frequently has difficulty keeping formula down, it is best to consult a doctor.

Milk Protein Allergy

Although it is uncommon for babies to be allergic to cow's milk, it can happen in up to 7% of babies under one year old. A milk allergy occurs when the baby's immune system overreacts to proteins in cow's milk, causing an allergic reaction. Symptoms of a milk allergy can vary and may include difficulty breathing, loose stools, blood in the stool, refusal to eat, irritability, or colic. Most children outgrow milk allergies by the age of five. If you suspect your baby has a milk allergy, consult a doctor.

Infections

In some cases, vomiting may be caused by infections or illnesses such as gastroenteritis, commonly known as the stomach flu. This can cause vomiting, diarrhoea, and a mild fever. If your baby has the stomach flu, it usually passes within a day or two without treatment.

Reflux

Reflux, or gastroesophageal reflux (GER), is a common condition in infants where food and stomach acid travel back up from the stomach to the oesophagus. This can irritate the throat and cause gagging and vomiting. Reflux is often caused by overfeeding or swallowing air while feeding. Most babies outgrow reflux by the time they are one year old. Lifestyle changes, such as keeping the baby upright for at least 30 minutes after feeding and feeding smaller amounts more frequently, can help manage reflux. In some cases, reflux medications may be recommended.

How to prevent vomiting

It is common for newborns to throw up formula, as their digestive systems are still developing. However, if your baby frequently struggles to keep formula down, consult a doctor.

Burp your baby

Babies often swallow air while feeding, which can make them uncomfortable and trigger vomiting. Burp your baby after every feed to prevent this.

Feed your baby smaller amounts

Babies have tiny stomachs, so drinking too much formula at once can cause vomiting. Feed your baby smaller amounts of formula more frequently to prevent overfilling their stomach.

Feed your baby slowly

Feeding your baby too fast may cause them to gulp down air, leading to vomiting. Feed your baby slowly and avoid jiggling, bouncing, or playing with them right after feedings.

Hold your baby upright after feeding

Keep your baby upright for at least 30 minutes after feeding. Holding your baby is best, as the way they sit in an infant seat can make spitting up more likely.

Use a smaller bottle and nipple

Check your baby's bottle and nipple size. Ensure the bottle is just big enough for a few ounces of milk, and the nipple hole is not too big. Fast-flow nipples can give your baby more milk than they can handle.

Check your baby's formula

The ingredients in your baby's formula may be causing an allergic reaction. Consult your baby's doctor about trying a different formula.

Dress your baby in loose clothing

Make sure your baby's clothing and diaper are not too tight, as this can put pressure on their stomach and trigger vomiting.

When to seek medical advice

While it is normal for newborns to throw up formula, there are some instances where you should seek medical advice.

Firstly, if your baby is vomiting forcefully, isn't gaining weight, is unusually sleepy or weak, or has blood in their vomit, you should contact your doctor immediately. Additionally, if your baby has green bile in their vomit, this could be a sign of pyloric stenosis, which requires surgery.

If your baby is showing signs of dehydration, you should also seek medical advice. Signs of dehydration include crying without shedding tears, floppiness when picked up, and no wet diapers for 8 to 12 hours. Dehydration can occur when vomiting is accompanied by watery diarrhoea.

If your baby's vomiting lasts for more than 24 hours, you should also contact your doctor. This could indicate a more serious cause, such as a kidney infection.

If your baby has a fever, particularly if they are less than 12 weeks old, you should be cautious and seek medical advice. Do not give your baby any fever medicine before they have been seen by a doctor.

If your baby has any other unusual symptoms or you are concerned about their health, it is always best to err on the side of caution and seek medical advice.
