It's going to be really really hard for me to change my name, but I'm going to do it. I'm very close with my family, and I have 2 brothers who are both married, so everyone has my last name. Leaving that name behind is going to be tough big time for me. But at the end of the day, I don't want to have a different last name than my kids. So I'll do it! I'm hoping it will get less weird as time goes on. Also I know FI would be super pissed (well, sad I guess) if I didn't take his last name. It's important to him. I'm going use my maiden name in one of my children's names (probably as a middle name).
I've also considered getting rid of my middle name as it is now (Elizabeth, which I don't really care for) and putting my maiden name as my new middle name. I know some people that are doing that and I kinda like it! If I don't, my new initials are going to be HEE! How ugly!
