How does adding a second child affect the love for the first? : Parenting

I know this sounds super silly, because I will love my children no matter what, but can someone tell me how the transition was from 1 to 2 kids?

I am absolutely in love with my daughter (9 months) and I’m scared about what will happen when my next child is born in April. I’m still a relatively new mom. Can anyone give me tips? Does your love just grow? Is it a “different” type of love for each child? How do I ensure my daughter gets as much love as she does now when she has a sibling? Will I subconsciously have a “favourite” child? My husbands mother favoured him and I don’t want that to happen with my children.
