My DS (5 in a week's time) (awaiting dx of autism) went floppy several times, lay down in muddy grass, licked pavement, ate sycamores leaves and tried to run off several times, while I tried to restrain him/pull him up at school pick up time. He's not always like this, but it took us forever to get home. Any tips or advice from parents who have encountered similar. I don't want to have to keep pulling him up or restraining him, but I don't want him to get hurt (ie knocked down crossing the road). Should I buy some reins? I just don't know what to do! He has to wear a high visibility jacket at school (mainstream) because he keeps running into the car park.
