worrying about having my second baby.

I'm a worry wart, I get it from my mom unfortunately. I'm pregnant with my second, and for some reason I'm worrying about my daughter.

It's probably just hormones, but for some reason I'm worried she's going to feel ignored or alone when baby comes, or I'm not going to be good enough. like I can't manage time between or with the two.

it literally is making me sad thinking about it. obviously I'll get her to "help" as much as a two and a half year old can.

but did/do any of you moms worry about the same thing? any advice or experience would be greatly appreciated!
