Infantile diarrhea is a common symptom, usually caused by infection, food allergy or indigestion. Here are some ways to stop diarrhea:

1. Give your baby enough water and electrolyte. Diarrhea can cause your baby to lose water and important electrolytes, so it needs to be replenished in time. You can give your baby some glucose saline, coconut milk or diluted juice.

2. Feed the baby digestible food. During the baby's diarrhea, you should avoid giving your baby greasy, spicy or indigestible food. You can choose some light and digestible foods, such as rice porridge, noodles and steamed bread.

3. Give the baby medicine. If the baby has severe diarrhea, you can consider giving the baby some medicine to relieve the symptoms. However, it should be noted that you should not give drugs to your baby at will. You'd better consult a doctor first.

4. Pay attention to hygiene habits. Diarrhea is usually caused by bacterial or viral infection, so we should pay attention to hygiene habits, keep the environment clean and tidy, and wash our hands frequently.

In short, parents should take timely measures to deal with the baby's diarrhea to avoid getting worse. If the situation is serious or lasts for a long time, it is recommended to seek medical advice in time.
