Baby #2....

So husband and I are finally haveing baby #2 after 9 yrs of infertility. We had to do

IVF

....Anyways lately ive been feeling weird about this pregnancy as if maybe it was a mistake. We have a 10 yr old daughter who im 100% contempt with. Her and I are inseparable and we have an amazing bond. Baby #2 will be here and im like "uh oh". Am I ready to share my love with another child and take attention away from our daughter?! I know this seems silly but its been her and I for 10 yrs. My husband is Military so hes gone often so weve literally had no one but each other....Anyone else ever felt this way?
