Keep in mind that Tx-2 will be live supervision with your QST Master Trainer, who will support your work with the child and the parent. It will be helpful if you arrange for another person to hold the camera (not the caregiver you are training, but can be a second caregiver), and if you will be using Bluetooth earbuds (which will limit the sounds in the room and make it easier for the child). Please coordinate the scheduling and arrangements of the live supervision Tx with your Master Trainer.
