Drinking ice water will not affect a nursing mother because the composition and temperature of the breast milk produced after drinking ice water will not change, so it will not have an adverse effect on the baby. However, if the mother has symptoms such as enteritis or diarrhea after drinking ice water, viruses or bacteria can easily be transmitted to the baby through the milk and cause discomfort. So if you have the habit of drinking ice water on a regular basis, you can continue to drink ice water. If you don’t have the habit of drinking ice water on a regular basis, it is not recommended to drink ice water during breastfeeding because it will easily cause intestinal discomfort to the mother and thus affect the baby.
