What substance should a lactating mother avoid?

A lactating mother should be mindful of her caffeine consumption, as caffeine can pass through breast milk and potentially affect the sleeping patterns and behavior of the nursing infant. While moderate caffeine intake is generally considered safe, excessive consumption may lead to irritability and restlessness in the baby. Health authorities often recommend limiting caffeine intake to around 300 mg per day, which is roughly equivalent to two to three cups of coffee.

In contrast, protein and vegetables are important components of a lactating mother’s diet, as they provide essential nutrients required for both her health and milk production. Water is crucial for hydration, especially for nursing mothers, to maintain milk supply. Thus, it's important for lactating women to be cautious about caffeine while ensuring adequate intake of other foods and fluids that support their nutritional needs.
