I agree with the great feedback you've been getting so far...less is more...and remember that though the day you tell them will be painful - you will only have to tell them once - (well, she will have to tell them...your silence will speak volumes to your children) -- after that day, you can show them all they need to know about what you value by giving them the best examples through your actions...though the occasional, calm conversation with one's children can do wonders for one's sense of hope...
