On our first visit to the lactation consultant, we learned that John Robert was "tongue-tied". His lingual frenulum--the part of your tongue that attaches it to the bottom of your mouth--was shorter than normal. This meant that the tip of his tongue was held tight and he wasn't able to use it like he should while breastfeeding.
Our GP referred us to an ENT, who successfully "clipped" his tongue on Tuesday of this week. I wasn't at the appointment, and Megan wasn't allowed in the room when they did it, but everything went well. You could tell a difference right away. He did better at breastfeeding immediately--though he still needs practice. For the first day or so, he looked puzzled by the new sensations in his mouth, and you could watch him discover his tongue. It has been sore, and he's taking a little Baby Tylenol for pain relief, but I think he's recovering from that now and he'll be just fine.
