Many infants have one or more blocked tear ducts at the time of their birth. Newborns do not actually produce tears until they are a few weeks old, but after that time if you notice that your baby’s crying is not producing tears, it may be due to a blocked tear duct. Your pediatrician can confirm if this is the case. Most tear ducts clear up by the time the baby is one year old without any medical intervention.

Your baby’s bowel movements will tell you a lot about their health, their diet, and how their stomach is doing. In order to detect when something is up, you will need to pay close attention to the daily occurrences and patterns. The color, consistency, and frequency are all important factors. Any sudden changes or inconsistency with their bowel movements may indicate illness. However, just making mental or written notes is usually enough. No samples are needed unless requested by your pediatrician.
