That's brilliant, broody! I'm really impressed. And don't worry about that old couple - you've the right to feed your baby!
I stopped by the hospital breastfeeding centre today, as we were there for a hip scan. They thought Tessa's lip looked normal, but wouldn't recheck her tongue. I'm not sure what to think. She really looked a lot more like the 'problem' photos on the link than 'normal'. I'm also getting confused about the possible connection to 'high arched palate' and too-small upper jaw. I had the latter - as a teenager I had to have a palate spreader which (painfully) cranked my upper from nesting inside my lower jaw to the reverse, which is the normal state of affairs. This made room for all my teeth, one of which was coming in in the gums above another tooth (they had pulled its baby tooth to make room for the earlier adult tooth), and I got braces to pull it down into place.
The breastfeeding lady said that was caused by bottle feeding, not anything to do with the tongue, and that there is a whole generation where it is really common. I'm willing (and would love to!) believe that bottle feeding was the cause and if I BF Tessa she won't suffer this, but I'm a little skeptical as I'm not sure she completely understood me. I wasn't aware that palate spreaders were common, and I think she may have thought I was talking about braces (she talked really fast and it was hard to get a word in - I'm not sure how much she listened to me). I haven't met anyone else who had a spreader and most people I talk to have never heard of them. Are they in fact common? Do you all know people who had them? (it's this thing that goes across the palate and has a little crank that is turned and pushes the jaw apart a fraction of a mm every night for a year or however long is needed - I had to lie on the bed with my head hanging back and my Mum turned the crank, which hurt quite a bit, as it felt like my skull was cracking, which I suppose it was in tiny, tiny movements).
I really want to believe everything is fine and I don't have to pursue anything more, but it may be worth checking a little more in case doing something now could avoid dental problems in the future.
Argh, sorry to go on so long. It's just I find the whole thing so confusing and I want to take the easy way to just believe nothing is wrong, but worry it might be trading a little potentially annoying investigation now against a year of teenage pain.
