Very belated wedding gift ideas

So the females in our family got married a few years ago and at the time I was a poor student and couldn't get them anything for a wedding present. Suffice it to say, all those years paid off and I'm in a pretty well paying job. They all have kids now but I haven't forgotten the fact that I never got them wedding gifts and I'd like to get them each something. However I'm kind of at a complete loss on what to get them, I was thinking like gift cards to an airline or a nice restaurant but I'm not really sure. Young families of reddit with small kids/babies, what do you think you would like ilto receive in this situation?
