So my FI and I are finally tying the knot after being together for over 8 years. We have a child and a house together already. I'm getting asked what we want for a wedding gift but we have no intention or really any need of any household items. do we really need to register?
Re: should we even register
The rest of the guests will see your tiny registry and go "oh! They have a tiny registry, obviously they'd prefer checks."
Problem solved, no pile of toasters.
While a registry can be a useful tool (it is just a glorified wish list that allows you to indirectly indicate what you might like as a gift), you don't have to register just because people think you should. It is not rude not to register or to decline to pre-select gifts for people just because they want to give you something. If you don't want to keep a gift you receive, you are entitled to discreetly dispose of it.
If you aren't registering, I'd say to anyone who asks about a registry, "We're not registered, but we look forward to seeing you at the wedding-that's what's most important to us." I wouldn't say "your presence is our present" unless someone specifically asks you.
