Need advice

So I am having my second child, it's a boy and he is due In september I am worried about loving one child more than the other. I know it seems stupid but I seriously worry about it. Like what if I love my daughter more than my son or my son more than my daughter. Am I just being weird thinking that I might feel this way?? Please tell me I am not crazy for worrying about something like this. Like will I want to be with my son more than my daughter. It keeps me up most nights thinking this and I'm upset about it.
