Wedding celebration question

Definitely send out invitations to the wedding celebration! Just be clear that the couple is already married, and that this is their reception/celebration of marriage. I wouldn't include their registry on the invites, though if anyone asks for that information, you can certainly give them the info at that time.

Invitations don’t really have the registry info. But people will usually contact you as the mom and ask if they are registered, so you can give that info then.

Invites are fine. Registry info is only given verbally when guests ask for it.

I don't think an "invitation" this early on is necessary, but if it's that great a concern, then a save-the-date might be helpful. Then you can do the official invitation closer to the time being. As to the registry, that's up to your son and his wife. If they had a registry to begin with, then ask them if it's okay to share it. Otherwise, don't make one up for them.

Your son and daughter-in-law will send out invitations to their celebration when they are ready to. 2022 is still a long way away and the celebration may be delayed if it is dependent on when their house is finished (after all, construction is often delayed). They may also decide later down the line not to have a celebration altogether. On this basis, I think sending out invitations (or making an announcement) would be premature.

As to the gift registry, where I come from, we know that celebrations involve gifts and prefer guidance as to what to gift. In my experience on WW, I understand that Americans find the practice of expressly mentioning a gift registry/wishing well distasteful.
