Introduction
In general, a newborn baby turning red and making grunting or whimpering sounds during breastfeeding in the postpartum period (sitting the month) may be related to factors such as indigestion, lactose intolerance, gastroesophageal reflux disease (GERD), respiratory infection, or infantile colic. If discomfort occurs, it is recommended to seek medical attention promptly and receive symptomatic treatment under medical guidance. Parents are advised to closely monitor their baby's condition, seek timely medical care, and learn scientific feeding methods, which can help alleviate symptoms.

Under normal circumstances, a baby's face turning red and making grunting or whimpering sounds during breastfeeding in the postpartum period (sitting the month) may be related to factors such as indigestion, lactose intolerance, gastroesophageal reflux disease (GERD), respiratory infection, or infantile colic. If discomfort occurs, it is recommended to seek medical attention promptly and receive symptomatic treatment under the guidance of a healthcare provider. Specific analysis is as follows:

1. Indigestion

A baby’s digestive system is not yet fully matured. Feeding too quickly or excessive milk intake may lead to indigestion, causing the baby’s face to turn red and grunt. It is recommended to adjust feeding methods by allowing the baby to suckle slowly and reducing air swallowing.

2. Lactose Intolerance

In cases of lactose intolerance, insufficient lactase enzyme activity in the baby’s body prevents complete breakdown of lactose. Undigested lactose ferments in the intestines, producing gas that leads to bloating and abdominal pain. This manifests as facial flushing and unusual noises during feeding. It is recommended to use low-lactose or lactose-free formula for feeding.

3. Gastroesophageal Reflux Disease (GERD)

GERD results from impaired anti-reflux structures or functions and reduced esophageal clearance. In babies, the lower esophageal sphincter function is immature, allowing stomach acid and contents to flow back into the esophagus, irritating the mucosa and causing discomfort—evident as facial flushing during feeding. Symptoms may include spitting up, regurgitation, and night-time crying. Treatment under medical supervision may include pediatric medications such as Xiaor Wei Bao Pian (Pediatric Stomach Pills), Xiao'er Jianpi Wan (Pediatric Spleen-Strengthening Pills), or Jianwei Xiaoshi Pian (Digestive Aid Tablets).

4. Respiratory Infection

Respiratory infections may be caused by bacteria, viruses, or exposure to cold. When affected, babies need to exert more effort to breathe while feeding, leading to facial flushing and grunting. Symptoms may also include fever and cough. Under medical guidance, treatment may involve antibiotics such as Roxithromycin tablets, Azithromycin capsules, or Cefaclor granules.

5. Infantile Colic

Colic may result from excessive intestinal gas or uncoordinated intestinal motility. Breastfeeding may intensify discomfort, causing bloating and abdominal pain, which leads to facial flushing and whimpering. Other symptoms may include paroxysmal crying and abdominal tension. Medications such as Atropine tablets, Belladonna extract tablets, or Raceanisodamine tablets may be used under medical supervision.

Parents are advised to closely monitor their baby’s condition. If any concerns arise, prompt medical consultation is recommended. Learning scientific feeding practices can help alleviate symptoms.
