Baby number 2

Questions for you mommas I'm pregnant with baby number 2 and couldn't be happier but I'm concerned I love my unborn baby and all but it's not like the deep love and connection I have with my son. And i can't remember if it was like this with my son when I was pregnant with him. Is it that I haven't met my baby girl yet and it still doesn't feel completely real till they are here and that is why I don't have that deep loving connection? Please help... Having baby number 2 is so exciting but there are these types of things I worry about...
