My in-laws have a rug, and it started unraveling while my 3.5 year old nephew was running around the living room. I saw him fall down then start crying, I rushed over and saw some string wrapped around his big toe. The string is similar to fishing line. It had gotten knotted up and when he got caught it acted like a noose. He's still crying about his toe about 30 minutes later. Does anyone have a recommendation for his parents? They are trying to decide if they should take him to the hospital tonight.
