AvidReader brings up an EXCELLENT point. I know you might think your teenage son or daughter could choose their religion with good thought.

But what about your infant child? Are you going to do a blessing in the LDS church, or a christening? The baby sure ain't going to decide.

What about your 8 year old child? Do they really know enough to choose between the two religions? That's when the LDS baptise.

I know nothing about first communion since I wasn't raised Catholic, but that happens somewhere in childhood too.

There's a lot to think about.
