I've never had dreams about taking the baby out and then putting them back in my uterus, but my favorite pregnancy dream I had was before I even realized I was pregnant. In my dream I came home from work to get some lunch and went to the bathroom, where I realized I was in labor. I reached down and grabbed the baby, looked at her happily then walked out, handed her to my husband and told him we finally had a girl (we have three boys) and that I had to get back to work. Haha. Kind of relates to another thread theme we have going here, doesn't it? Now that I think about it, from what I remember all of my pregnancies have been correct about the gender, all 4 times.
I haven't had a lot of dreams specifically about the baby this time around, but last night I did dream that I was an International super spy and my oldest son was an undercover villain who was trying to kill me. It was all very 60's James Bond. Kinda fun. I love the crazy pregnancy dreams!
