Mom guilt?

Have any other moms gone through feeling guilty about having another baby?

I’m currently pregnant with my second child and all I can think about at the minute is that my baby girl isn’t going to be my only child anymore, I worry that I won’t be giving her the attention she needs or deserves and that she’ll feel left out. I also worry that I couldn’t love anyone else the same as my little girl, she means the world to me and I’ve never felt love like it so I wonder how it’s possible to feel that love for another little person.
