After the crappy start to the BB year with a member losing her husband, then Uncle Amy and Lulu, then the babies born sleeping that didn't even get a chance at life, it really shook me up and I organized life insurance for DH and I so at least the surviver will be alright financially if anything happened to one of us.
I do worry about myself dying and leaving them, also if DH takes the kids out I sometimes end up in tears at the thought of something happening and them not coming home - they are my whole world.
