I believe legalizing marriage, normalizing LGBTQ couples' status first to prove the general society that they're not actually some sick perverted sickos before we allow children adoption, should be the first step. Also waiting for the old people to die out, to put it bluntly.
Keep in mind Poland is still a hugely conservative society, in full grasp of the Catholic church. It's changing, you can clearly see the trend, but on the other hand our current government is still actively painting LGBTQ+ as some sort of harmful ideology or what not. We have a long way to come.
Not OP, but same situation. I usually don't, but my mother who lives far from us does every day. We take a lot of photos and videos, she gets to watch them and she's up to speed on our kids' lives, can talk to them about stuff they did today, etc. We feel like it lets her be a part of their lives in a way.
Then you have that Google Photos feature where you get automatically created mini albums like "they grow up so fast" or "now vs then", it will compile a couple of photos from 7, 6, 5, ... Years ago and we watch those religiously, often coming back to the particular event from which some photo is. We can spend an entire evening going through older photos like that.
