Concussion junction… what’s your function?

Home (for the second time this year) with a child who has a concussion.  Don’t worry, he’s fine – just needs to rest.  We have a family of 4.  This year two of us has had concussions and the other has broken their nose (plus a sister-in-law that broke her face).  If my husband can just do something minor – (stung by a nettle?) – then we can have a really cool Christmas card.
