16 weeks preggo and time to study! I have a 3.5 year old whose 4th birthday is 2 days past my due date. She is very, very wonderfully attached to me, a little shy, and doesn't like independent play yet. Her whole world has been her in the center of our lives. I am so afraid of the negative impact the new baby may have on my sweet girl. I know there will be positives but I'm daunted by the potential negatives. I'm looking for excellent book suggestions on the subject of how to best help a sibling accept a new baby. AND your personal ideas and suggestions based on your experience.
