Louisa- our age has nothing to do with it, nor ages of gc, i have quite a few ranged from 26yrs down to just 3yrs and im only 62.But ive seen these 'geandparent' cards on moonpig etc and still dont see why we, as a new grandparent, would need congratulating for it in an actual card- maybe face to face if we bumped into a close friend, but even then i'd expect them to perhaps be offering those congrats to my own adult child via me, for the new arrival- i.e. "tell your daughter congratulations from me', but i myself havent done anything to produce the gc so would expect only cards for the parents.
