Both my wedding and baby registries would be totally different if I could do them over again knowing what we might actually need. I know there are tons of lists out there, but everyone's situation is so unique.

I would have not put any boutique-rarely used items on my registry (sushi dish set? mandolin slicer? NEVER USED). We got so much stuff from our registry but to this very day do not have a complete dish set for everyday use, nor do we have enough sheets. I should have put more everyday stuff on there.

As for the baby registry, I should have put a ton of bottles on there as well as basic clothes in every size (I didn't put any clothes on there at all). We have a ton of mis-matched onesies that don't go with anything. Pants that don't match anything. And clothing that is the wrong season/itchy/scratchy/uncomfortable/will never be worn.
