Jenn, I'm so glad you're enjoying TSD! A is a red belt, E a brown (!!!!), and M finished Little Dragons and is now an orange belt and will be joining the "big kids" in Sept. Iris is starting Tiny Tigers (technically a year early, but she's practically grown up there!) in September, and the kids are trying to talk me into joining. I just might! (The world's oldest white belt, lol!)
Liza, I don't think I'd request "no students," but I would be pretty vocal about telling them how I prefer to be treated. "Hi, I realise you're in training, but this is my baby we're talking about, and I'd really appreciate you not whispering. And please, keep the screen pointed in my direction, I do like to see what's going on."
Good luck, it can be tough to advocate for yourself when you are counting on others to help you with information.
I loved the ultrasound I had with my last baby. It was an early one (I don't like ultrasounds and generally avoid them) but I have anxiety issues and wanted to make sure everything was OK. He asked me right away what I wanted to know, and I told him: "I want to see two healthy lungs, two healthy kidneys, a pumping heart with four chambers, a brain and brain stem, a complete and enclosed spinal column, four limbs with proper attachments, an umbilicus with the right number of arteries, etc." He went through every single thing with me, and showed me a totally healthy baby, and made the rest of my unexpected pregnancy so much easier! Maybe you could go in with a list of what you'd like to know about (limbs, lungs, heart, etc) and have them show you each one? THat way if you do get a student, they get a bit of training, and you still get some attention paid to your needs?
