For Fen;
Now is the time to write down all the things that you and your partner like to do; be it shopping, reading, flight sims, gazing out the window, etc. Put that piece of paper into an envelope and lovingly store away.
On sproglets second birthday, open said envelope and regale one's partner with how life used to be. I can guarantee the conversation will go;
"Did we really do that?"
"Well it's written down here but I'm not sure, I don't remember"
"No, neither do I"
