I found my 2 yr old grandson had opened my 1mg xxanex. A few were around him, but I caught it pretty quick.. I opened his mouth and didnt see any signs he has any in his mouth.. I have kept him awake for a hour. He just fell asleep because its way past his bedtime.. he acted normal until then.. I dont know if that was enough time.. I dont think he ate one. But just wanted to watch for any signs..
