I thought it was a GREAT idea tho...and i also think he needs something to redirect (as Medusa said). I kept thinking about a skoooosh (sp) ball. The kind with all the "speggetti" like tendrils. Maybe he could pull on those to help keep himself from pulling at his eyelashes and eyebrows. I also think it might be a good idea to find out why he is doing it. You could also do a functional behavioral analysis to find out what is causing him to do it. Have you talked to his teacher about it ? They could do the FBA at school and you do it at home. Then you would have a better idea what is causing the stress and maybe find a way to eliminate it.
