Glad to hear the risk is low for one parent with UC. It has always been my biggest fear and, for a period, I considered not having children so UC would die with me.
Now I quietly pray and carefully watch. My child is also aware of my history, though I try to keep it relatively light. I make sure we keep close tabs on any digestive oddities, as well.
It is very important for our children to have good knowledge of our condition so, if they or their own children are faced with it, treatment is not so delayed.
It was 5 years before the severity of my UC was properly diagnosed. By then the docs couldn't believe I was still carrying on a relatively "normal" existence....at least as it appeared to the outside world. Like Jan, by the end, I was down to 89 pounds. Scary stuff.
