Hi, I am new here. This is a great site and I'm really pleased to see such an active sn area to post. My son is 3 and a half and devel delayed and he seems to have processing issues. We dont have a dx yet for him but he gets OT, ST, PT and special ed services. My question is about a behavior he does with walking along walls and stairing at the wall, mostly if there are lines along the wall and walking rather quickly. He does this also with counter tops, or other lined areas that are his head height. He usually does it mostly if he is tired or stressed or there is too much sensory stimulation going on around him. At school they have walked behind him and held their hands against the sides of his eyes to shield his vision and to look ahead (think like a horses eye shield). He doesn't look forward at all when he does this so it's pretty unsafe. He bumps into people and things. He really wants to look at the wall so when they block his vision he doesn't get the impact he wants and moves on to something more appropriate. This is ok at a more controlled area like school but I'm thinking for other public areas like grocery store etc. He can do well in these areas some times. I havn't seen anything about this kind of stimming on other sites or books and we're looking for ideas to help him. We've thought of something he could hold like pics of a train track or something visual like that. My sister had an idea (could work at certain times) of saying something like, "I see you need some time to walk and look at the wall. How about we walk for XX amount of time and then we'll go back to __________ " (whatever it is that he needed a break from). We sort of do this now but making it more concrete and more like a tool to use. Any ideas, suggestions or anyone known of this kind of behavior before?
