Damien - I am so sorry to read this! I know too well what it is like. My daughter was only 14 months old when Ken died so she was too young to fully understand. I try to keep his memory alive as much as possible - that was his biggest fear that she wouldn't remember him. I look at her every day and see Ken in her and I am so thankful she is here and I know she is here for a reason just as your two kids are. If it weren't for her I wouldn't have gotten out of bed each day after Ken passed away. Start with getting through each minute of the day and work from there. Hold your kids extra tight and know that Katie is watching over all of you all the time.
