Do you love your other children the same as your firstborn?

Forgive me for the odd question folks, it's actually genuine. I ask this because I have a little baby. Well I guess she's not so little any more. She's almost 11 months. I'm in a comfortable situation. Hubby has a good job, we have a decent income etc...so naturally the next thing to do is to have more kids right? I mean, that's kind of what I'm getting the impression of anyhow. I just don't know if having one is enough or if one is all I want. We have a pretty great dynamic with just the three of us. I'm a little worried that if we have another baby that it will ruin that dynamic, if I would be as in love with our second baby like our first. How did you feel with your subsequent children? What was the motivation to have more children, or to have only one? Thank you for your input, I appreciate it.
