Help - double surname

I have a double barrel surname and it's a nightmare lol. Mainly because I love both of my names and because I was given it because my parents weren't married and my mum didn't want to give up her name. So it started as a feminist statement.

However - I am also not married to my long term partner, who also has two surnames.

And now we have a baby so the question of what to call him was really long. You can't quad barrel a baby!

So now the baby just has his "main" surname and the feminist dream has ended which makes me sad. The hyphen is also a bit annoying on forms but that's not really a problem.
Fully aware I could have played it differently but that's just where we are!

I had a double-barrelled surname twice. As a child I had both my parents names... And it was a total nightmare. Ppl struggled to spell both of them as well, just to make it worse 🤣 once I was 19 I deed-polled and dropped one of them. Then a few years later I got married and double-barrelled again (my husband also took my surname on) and that was less of a hassle, as an adult, and also it was my free choice and kinda felt like a novelty because I was excited to be married? I'm divorced now lol. When I had my daughter, her dad (who I wasn't married to) wanted to double-barrel, but I decided against it.

Personally I think if you don't double-barrel it's a little easier as the second surname can be used as the "official" one but if the parents are not married I think it's just better if the child has the mum's name.
