You were building bonds and enriching their brains which is what makes them who they are today!
Fully agree. Our 18 year old remembers little if asked directly, but will recognise things if prompted, such as when we look through photo albums or sort out the loft and find old games, cuddly toys, books, etc. He also remembers things if we go back to the same places, such as holiday resorts, theme parks, etc. It's all about "triggers".
But yes, the more important thing is that he enjoyed it at the time, remembered things short term, learned from it, gained life experiences, etc etc. So much change happens in the formative years, so much is new, then before you know it, they're off to primary school, then secondary, then Uni, with teen years, relationships, etc, it's no surprise that teens don't automatically remember things when so much has changed in their short lives.
Just remember whatever you did has helped mould them into who they are today.
