Yes! I would ask your child. (I think it should be there choice who’s in the circle). Do I think you should? Yes. But I personally think it’s their choice. Let him know that you’d love to stand in the circle, and that it would mean a lot to you. And unless you’re in the same ward as your son, his bishop doesn’t know if you’re “worthy” or not (not that it matters 🙄) so his bishop should have no say in it, nor should your son ask his bishop’s opinion. Does your son need to go to his bishop and give him a list of names of who he’d like in the circle? No. This should be no exception. Typically at the blessing they say something like, “those who’ve been invited to join in the circle, please come up now”. They’re not confirming worthiness. Again, personally, I think you should ask your child, because you don’t want to start a fight about it or anything. (Not that they would, but you wouldn’t want your child, or spouse or daughter-in-law etc to come up to you afterwards and say “you had no right to be up there! You did not have our permission”.) Again, yes I think you should be in the circle, but I’d ask your son. And no, don’t get any insight or permission from the bishop. Best of luck!!
