What should I do if my baby has diarrhea after eating crabs during breastfeeding?

Patient's question:

Hello
My baby is now 7 months old. The day before yesterday, after eating three crabs, my child developed many small red spots on their body and was not breathing well. They also had some diarrhea. It has been two days and it hasn’t gone away. What should I do?

Doctor's answer:

The meat of crabs is delicious and nutritious, and many mothers enjoy eating it, but it may not be suitable for babies. If a breastfeeding mother consumes crabs, which contain high purine and other substances, and are also considered a cold food, babies with weaker constitutions and poor cold tolerance may absorb the nutrients and coldness through breast milk, potentially leading to diarrhea symptoms.
What should be done if a baby has diarrhea? The mother can use a dietary remedy: take fresh apples, rinse them thoroughly, chop them with the skin on, add water and salt to a pot, cook them into a soup, and then feed it to the baby.
