Baby #2 Guilt?

I recently found out I’m pregnant with baby #2. By the time this baby is born, my kids will be 19 months apart. This pregnancy was planned and everything, but since finding out - I’ve been having huge feelings of guilt for my little girl. It’s hard for me to imagine loving someone as much as I love her. I know it sounds silly but I feel like I’m taking love away from her by adding a new baby. Logically I know I won’t love my first born any less but are these feelings normal? Or is it just me?

How do I cope or change my way of thinking??
