The bomb is one thing (the kids already have an idea that something's way off), being there for the emotional fallout is another thing entirely.
That is love, that is being there, that is being a parent. Here's a prayer to all the love, hugs, tears, cuddles, quiet strength, finding laughter, being open.. the love that only one person can give them.. which comes from you. Be their rock was their emotions crash against you. Reassure them that you are not going anywhere.
Well.. really... do what works for you.. and you're a pretty incredible guy.. I figure that makes you an exponentially amazing dad.
*hugs*
About resilience.. children learn from their parents. They will learn from you. Let your love guide you from the 25 meter mark and beyond.
