If a tight frenulum does not impact nursing there is no reason to clip it at this point. That is...unless you can find a doctor that will clip it without the use of anesthesia and a hospital stay (I don't remember the age it turns from a quick outpatient procedure to a serious inpatient operation). It might break on it's own, as it is already tearing. As for speech impediments, about 1 out of 20 people are born with tongue ties, and not nearly that many people have speech impediments. Most tongue ties resolve on their own by stretching or breaking. Since your babe had no problem nursing, her tie must be very small. Good luck in your decision! My son had a pretty serious tongue tie that we clipped when he was 2 days old, as he could not nurse, now he has no issues with it!
