Scully is right Flower...you need to specify who you want to act as caregivers for your son...that means eliminating who you don't want.
I'm like you, all my family are in the borg except one brother....however my kids are old enough now to decide what they want and which path they choose to take. Their father is still in the borg...so if anything happens to me, they will go directly to him. His borg influence is no longer effective...so it really isnt a problem for me, but I can see how tricky it can be if you're kids are still little and if you've only got JW relatives.
I guess I would want my kids to go to someone who loves them...whether JW or not. But thats just me Flower...doesn't mean to say it is right for you aye.
My thoughts.
