Hi MLeigh, I think it's no bad thing if you feel like baking, and it may remind him of what he misses about home. But I think the main thing is just to treat it as a single day which will hopefull pass pleasantly and have no expectations. It will be nice for S for you all to spend a little time together and then life will continue.
I can recall you posting about similar days in the past, where you guys have spent time together and H has continued on as he is. He may (or may not) continue do that for some time yet. I hope you have a nice time and take it for what it is - a pleasant interlude. And I hope your bundt cake rises (if that is what they should do...I have no idea what one is!)
Take care xx
