Does anyone have good articles/reading recommendations on developmentally appropriate behaviors (or misbehavior) for 3-year-olds, especially regarding sibling rivalry?
Here's a bit of background: I have a 3-year-old dd who is quite spirited, and a 4-week-old dd. DD1 has exhibited a number of behaviors recently that I expected - she's sometimes too excited/rough with her new sister, she tantrums more often, she doesn't listen to us as often, she whines. I see all of these behaviors as normal (though not desirable) reactions to the interruption in her life. My DP, on the other hand, thinks that we have the only 3-year-old who acts this way and that dd1 is the only sibling who has ever hit her baby sister. He believes that we've done something terribly wrong with dd1 for her to act in the way that I've described. Any help you could provide would be much appreciated - if not articles, then just sharing your own experience with sibling rivalry and general 3-year-old behavior. Thank you!
