Client getting 'stuck'

Hello all!

I have a non-verbal, PECS using ASD boy who becomes stuck in his routines at times, especially when something is removed mid-activity.  The items being removed are for his own safety and best interest.  However he is becoming 'stuck' for long periods in one activity because of this. 

Does anybody have any similar experience?  Any strategies used to try and avoid this? 

Distraction techniques sound like a good option to me, has anybody else attempted these?

Thanks!!
