This is not an insurmountable problem. There is a very simple procedure, that used to be quite common, called tongue clipping where the doctor cuts the tether beneath the tongue to allow the boy to extend it fully again. This article explains the issue and its history. Turns out that Finn's version of tongue-tie is the hardest to diagnose & treat, but if left untreated, it could cause problems in the future with speech & sinus development. This would also obviously effect the boy's chance of ever playing lead guitar in a rock band, if he can't even get his tongue out past his teeth.
Before getting any part of him cut, we got a second opinion from a woman who spent 18 years specializing in breastfeeding issues (thanks Dot!). When we showed her pictures of Finn's tongue & mouth she asked if she could use them to teach students what tongue-tie looks like. That was a pretty resounding second opinion. On Tuesday, we brought Finn back in to see the original doctor and to discuss tongue clipping. His weight was down even further, almost back to his birth weight, so after a quick discussion we decided to go ahead with the procedure. It took about 10 minutes. The baby had a local anesthetic, but still screamed bloody murder, which didn't help Kitty's state of mind as she held his head. Immediately after the procedure the baby is back on the breast and is fully healed within 24-hours. He didn't need Tylenol or anything, but Kitty could have used some painkillers.
In order to get his weight & energy back up while his breastfeeding improves, we started supplementing with formula. It's nasty tasting stuff, but he sucks it down and as of today had already gained back some weight. Everything appears to be moving in the right direction. His fussiness is down (for now), his sleeping is improved (he actually let us put him down for a little while) and he appears to be smiling for real (when he's not spitting up on us).
All in all, we're in a very good space and the boy continues to get better looking by the day. Here are some pics to prove it: http://gallery.mac.com/woodykit
We'll keep everyone posted with any new developments, but for now we're focusing on Finn's dancing lessons and Aunt Nicole & Uncle Keith's visit this weekend.
