When I took our almost-two-year-old to the ER for his stitches a couple weeks ago, they asked me what happened in a couple different ways, I could tell they were 'feeling out' the situation to make sure he really had clocked his face on the coffee table and that I hadn't smacked him upside the head or something.
I hope this situation just works itself out for you.
What an awful ordeal to have to go through.
