Planned baby but now had little doubts

Elysia • Baby girl born Feb 2019!! 👶💖 followed by 3 angel babies 👼

So this sounds awful but this baby is so so planned and super loved already but I have an 8 month old and I'm so excited to give her a sibling but now I'm wondering if I'm taking away the attention from her greatly or taking attention away from the newborn when it comes....I loved the first few weeks with my little girl with the cuddles etc

Is this normal? I know we will be fine and I'm sure this will go away

Heres my little girl
