Baby #2 mistake

I would never say this to anyone but sometimes I feel like baby #2 was a mistake. I mean, we definitely planned baby #2 but I’m so worried about how my 2 year old will feel. Will she still feel loved? Will she adjust? I know every first child has adjusted but I love her so much and I never want her to feel unloved. Can I love another child like I love her?

Are these feelings natural or am I just hormonal.
