Memorial/rememberance ideas...

So my due date is coming up this week but unfortunately my son was still born in September (23 weeks)

I'm looking for something to do in memory of him. I will be lighting his candle from his memory box but I want to do something else aswell. I'm not sure...

Does anyone have any nice ideas? My friend suggested going to the beach and setting a balloon/lantern free but I dont want to do that due to the danger to animals (one of my horses needed surgery because of a balloon once)

What are some good ideas?? Thank you in advance
