Self-soothing behaviors are usually quite unconscious, or automatic, for young children. But your concern is not unfounded, since children who display a behavior or characteristic of a neurointegrative sort may well display some other symptom as well. Be sure to talk about your observations with the pediatrician, and see if he thinks your daughter should be evaluated by a pediatric neurologist.
Hi. Thanks for responding. What made me think of tics was that it was repetitive, chaning, and she seems to be very hyper when she gets going with the noise. For example, yesterday when she came home from pre-school she made the clicking noise like 8 to 12 times in 2 minutes. I asked her "Why did you make that noise?" and shee seemed completely unaware she was doing it. If it were self-soothing would she be aware of it? Also, she has had some strange behavior lately. The other day, she took off her shoes and socks and started to lick her feet! I told her she shouldn't do that, feet are dirty ahd have germs. I have seen her lick her finger then rub the wet finger on her arm or leg. I'm not sure why she does this. She is an only child so I tend to over-analyze things she does, but because of the DX of apraxia I worry she may have some other conditions as well (comorbidity) - TS, ADHD, SDI. and YES, I am a worry wart! Thanks for your help.
To be frank, it is not clear that the noises are actually tics. My sense is that they are self-soothing mechanisms for her vs tics in the strict meaning of the word. If they are tics, one would wonder about the co-existence of motor tics, but this does not sound like an emerging Tourette's Disorder situation. However, be sure to discuss this with her pediatrician.
