Why has a 4-month-old baby suddenly stopped breastfeeding?

A 4-month-old baby suddenly refusing to breastfeed may be due to physiological factors or pathological causes, such as indigestion or oral ulcers. Appropriate management should be chosen based on the underlying cause. The specific analysis is as follows:

1. Physiological Factors

If the reduced milk intake is caused by a slow growth rate and decreased nutritional needs during the "nursing strike" phase, but the baby's mental state and physical development remain normal, this is generally considered a normal phenomenon that does not require special treatment.

2. Pathological Factors

1) Indigestion

If bloating, diarrhea, and reduced appetite caused by indigestion lead to refusal of breastfeeding, digestive aids such as compound digestive enzyme capsules, compound azintamide enteric-coated tablets, or multienzyme tablets may be used under medical guidance to improve digestion.

2) Oral Ulcers

If oral mucosa is damaged due to oral ulcers, breastfeeding may irritate the ulcer site, worsening pain and leading to refusal of feeding. Under medical supervision, medications such as Kangfuxin solution, drometrizole lozenges, or watermelon frost spray can be used to relieve pain and promote ulcer healing.

In addition, conditions such as thrush, common cold, or acute gastroenteritis may also be responsible. It is recommended to seek timely medical evaluation and follow doctor's instructions for treatment.
