Over the weekend I identified a tight labial frenulum (correct term???) on a friend's 11 mo baby. He has a tight upper lip that has never curled out (during breastfeeding or smiling) and we saw a tight fibrous tether that is anchored low and pushing his front teeth apart. He breastfeeds well and his tongue is OK. I looked under his lip because I recalled reading about this on Lactnet, but can't recall the discussion. Can anyone fill me in or point me in a useful direction for more information. Is there a need for intervention? The teeth are the only "problem" so far. Can it effect speech?
