S.O.
Hi, I don't have any experience with the licking. But my son was diagnosed with SID (Sensory Integrated Disfunction) at 16 months. We did all of the therapys that you are doing. He is now 4 years old and only has speech delays. So keep up with the therapy- It works! My son started off in the NICU for a week, so I have been there. Good Luck to you :)
