Second Baby guilt....

Alright y'all, My husband and I have been talking about trying for baby #2 in a few months. It's still awhile away but I can't help shake a feeling of guilt and sadness and i'm not pregnant yet. Our daughter, if we got pregnant the first month of trying, will be around 2.5 by the time the new baby comes. I just worry about if our daughter will not get enough attention and it makes me sad she will no longer be our only baby but i also would love another blessing and give her a sibling... is this normal? Also, i worry if i will love it as much, i know that sounds crazy! how do you get through it? Does this mean we aren't really ready for baby #2?
