Didn't quite know how to word the title sorry. My son is 4 in january and is autistic, he goes to a program run by the school district and they have helped tremendously Ok so he has a big thing about smelling things, this was extreme but occupational therapy 4x a week has lessened it dramatically however he has recently started wanting to smell roads as he is crossing. He will just drop down on hands and knees to smell. Obviously I hold his hand across the road but there are times where he pulls out of my hand. He does have a sense of danger around cars so does look and often just puts his head over the side of the pavement to do it. Any tips on how to approach this?
