I agree with Quinault. Each woman is different. But you may finding yourself falling in love with your baby
while he/she is still in your womb. The first flutterings you feel of the baby moving within you will take you by surprise. In time, you will sense when the baby is asleep and still and when it is active and moving around within. You may even see the sweep of a little foot or hand run down your side.
Then, when the baby is born, you will be overwhelmed when he/she arrive. Oxytocin (the bonding hormone) will kick in soon after you either breast feed or even if you pump out the milk. So try not to worry about what will come in the future. Trust God as much as you are able.
I have two children but wish I could have had more. They are both teenagers and I am still enjoying every moment I have with them.
* The first guy came a little early and had some problems initially (Jaundice, couple days in an incubator, feeding difficulties, later colic, hypersensitivity, sleeping for only two hours at time each night for 5 months!) But he and I still managed to bond even though I couldn't breast feed him and was completely exhausted. So even in difficult situations, bonding still can happen. And in spite of his initial temperamental difficulties, he has turned out to be a very relaxed, easy going guy, go figure?
