This may sound silly. But try not to overprepare the other child. I am not sure how old your oldest is. I think sometimes we think we need to talk about the new baby and what it will be like when it comes as much as possible. I did not do this. My oldest was about 22 months. He knew he was having a brother, but that is about it. We didnt dwell on it. When the baby came, he was excited, but not overly interested. He LOVES his brother. Constantly kissing him and trying to love on him. We have not had any issues of jealousy. I do try to do a lot of stuff alone with the big one so he does not feel left out. Good luck
