M.P.
When did you start with using the q-ti? It's possible that his body has adjusted to stimulation by q-tip and doesn't act without it. What did the doctor say about continuing to do this? I also say follow the doctor's lead. Perhaps you need more information from the doctor. Call and ask questions.
A week at Children's Hospital evaluation is thorough. I would work at letting go of my anxiety, follow medical instructions and wait and see.
