My question is similar to this question but not exactly the same. We are having our second child very soon. We have a 2 year old daughter and she is already beginning to understand that change is coming. I have read/heard nightmare stories about the jealousy of the first child against newborns. While we still have a chance, how can we potentially prevent or at least decrease any high levels of jealousy and resentment towards the new child by my daughter?
Spend one-on-one time with your daughter, as much as you can. Important now, while the sibling is still on his/her way, but critical once he/she gets here.
Also, find ways to include her in the day-to-day care of her new sibling. Can she fetch wipes/diapers/bibs? Would she want to help feed, when bottles are appropriate? Maybe she can do some coloring for the baby? My daughter, who was a little less than three when her brother arrived, loved drawing pictures to put into his crib in NICU, and when he was home, we posted them on his walls.
