Well, it can be a very normal feeling. I'm sorry that probably isn't much help, but it does seem first pregnancies are very special since everything is new and most are in awe that the woman's body can do what we do. I definitely was very blase about pregnancies 2 and 3. I didn't spend nearly the time I did with #1 on reading books and engrossing myself in every little twinge or movement. For one, there wasn't really time having a toddler to take care of too. And I think hormones do mess with our minds. Don't feel guilty. I know you want this baby, but it is just different set of emotions and that's okay. For us, baby #3 was definitely wanted, but there were times I couldn't even tell you how far along I was. It's hard to explain and I am probably not conveying just how much I do understand how you are feeling. I have an 18 month gap between #2 and #3 and I was feeling like #2 was just a baby herself and that I was cheating her out of her babyhood because I was tired and pregnancy doesn't really agree with me (I like the baby in the end though), but it turns out okay in the end. It's okay to focus on yourself, do the things you enjoy and take time to enjoy your first child. I'm sorry I'm not much help, but I did just want to let you know that what you are feeling is really okay.
