Why Newborns Often Spit Up: Causes and Physiology
Spitting up in newborns is a phenomenon that occurs in about 50-65% of infants during their first six months of life. It is related to the anatomical and physiological characteristics of the baby’s digestive system. In particular, the immaturity of the lower esophageal sphincter (LES) leads to the backward flow of stomach contents into the esophagus and mouth.
In infants, the sphincter does not reach full functional maturity until about 6 months, so spitting up is considered normal if it is not accompanied by painful symptoms or weight loss.
Key Causes of Spitting Up in Newborns
- Immaturity of the digestive system
- Overfeeding or feeding too quickly
- Swallowing air during feeding
- Gastroesophageal reflux (GER) as a physiological process
- Body position after feeding
How to Feed Properly to Reduce Spitting Up
Adjusting feeding technique is one of the most effective ways to reduce the frequency and volume of spitting up. In 2026, anti-colic bottles are popular on the Russian market, such as the Philips Avent Natural, priced between 900 and 1500 rubles for a set of two.
It is recommended to feed the baby in a semi-upright position, which reduces pressure on the stomach and decreases the likelihood of food reflux.
Feeding Tips
- Use bottles with an anti-colic system (for example, Dr.Brown’s Natural Flow, costing from 1200 rubles)
- Feed babies slowly, taking breaks to burp every 50-60 ml
- Avoid overfeeding — the optimal feeding volume depends on age and weight, for example, about 60-90 ml per feeding for a newborn
- Keep the baby in a semi-upright position during and for at least 20-30 minutes after feeding
Optimal Positions to Reduce Spitting Up
Properly positioning the baby after feeding is extremely important. A horizontal position promotes food entering the esophagus, so it is recommended to hold the baby upright for at least 20 minutes after feeding.
Rocking or placing the baby on their side carries the risk of breathing difficulties or discomfort, so experts from the Pediatric Research Institute (NII P) recommend placing the baby on their back with the head of the crib slightly elevated at 15-20 degrees.
Positioning Recommendations
- Upright position after feeding (hold in arms at about a 60-degree angle)
- Use adjustable baby cribs with a raised head end
- Avoid placing the baby on their stomach in the first months to reduce the risk of sudden infant death syndrome (SIDS)
When Spitting Up Becomes a Problem: Signs to See a Doctor
Spitting up is considered physiological if it does not lead to impaired weight gain and there are no signs of pain, crying, or distress after feeding. However, if spitting up is frequent and abundant (more than 30% of the food volume), accompanied by weight loss over 10% in the first weeks of life, or symptoms such as irritability, refusal to feed appear, a pediatrician should be consulted.
In 2026, in Moscow, the average waiting time for a pediatric consultation in public clinics is about 7 days, while in private clinics such as “SM-Clinic,” appointments are available within 1-2 days, with consultation fees starting at 3000 rubles.
Criteria for Urgent Medical Consultation
- Weight loss exceeding 10% of birth weight
- Heavy spitting up after every feeding
- Signs of dehydration (dry mucous membranes, infrequent urination)
- Persistent crying and distress
Use of Medications and Folk Remedies: What Is Allowed?
In most cases, medication is not required to treat spitting up in newborns. If GER causes significant discomfort and complications, a doctor may prescribe medications such as antacids or prokinetics. However, since 2026 in Russia, strict regulations govern the prescription of such drugs to children under 6 months.
Folk remedies (for example, dill water) may be used after consulting a doctor and only as a supplement to the main recommendations. The price of dill water in pharmacies ranges from 150 to 300 rubles per 100 ml.
Permitted Medications and Measures
- Antacids by doctor’s prescription (for example, Almagel — about 250 rubles per 100 ml)
- Physiological measures — proper feeding and positioning
- Folk remedies — dill water, only after pediatrician approval
