Lactobacillus drinks can be taken during breastfeeding. Generally these lactobacillus drinks contain no other ingredients that may affect breastfeeding except for more sugar and a small amount of lactobacillus. Lactobacillus drinks are just drinks that may contain a small amount of intestinal probiotics in the middle to help regulate the intestinal flora. The ingredients in these drinks are not secreted with breast milk. However, it is important to note that lactobacillus drinks can also contain a lot of sugar, so if you have diabetes during pregnancy, it is best to avoid drinking these drinks with a lot of sugar during breastfeeding to avoid causing blood sugar instability. These sugars can also lead to an increase in sugar in breast milk, which may also affect the baby’s sugar intake and affect the baby’s sugar metabolism, so try to drink less of these drinks containing a lot of sugar during breastfeeding.
