I had discussed with my DH keeping my maiden name before I got married, and he was OK with it (slightly NOT ok), but I think I got so caught up in wedding plans that I just couldn't get it straight in my head at the time. I also didn't want to deal with his parents (or mine), who wouldn't be happy about it, but would have had to go along with it if that's what I chose.
I did change my name, and I regret it. It's not a HUGE deal to me that I did, but I still think every so often that I'll change it back, or change it to my mother's maiden name. I'm 100% Italian, and I now have (a very lovely) WASPy name. Yeah, I love my husband just like all the other people who are going to come on the thread who took their DH's name (I've seen this thread before over the years...I started one once). But there's a certain sense of my identity that I feel I lost.
I haven't, and probably never would, change it at this point (I'm 51, married 25 years)...I just don't want to make the effort to then go and change every document. But I have told my daughters that I wish I hadn't, and that they don't have to (but it's fine with me if they do) change theirs...just to think about what they really want to do, and do it.
Had I not changed my name, we would have given the kids my DH's last name. Hyphenated names work well if they're short...my maiden name and married name are both 10 letters long.
Back when I got married, it wasn't as common to keep one's maiden name. Now, I'd go for it.
My DD had a teacher who was married and took her DH's name. Got divorced, took back her maiden name. Married again...took that DH's name.

If I ever got divorced (don't see it happening

), I'd take my maiden name back and stick with it!
Good luck with
your decision.
