My only advice is discipline and boundries. I have a 4 & a 2 1/2 yo and am pregnant, my kids know that that kind of behavior has a consequence Time Outs. Not that they don't test me from time to time. It is normal for the older sibling to go through a bit of an emotional difficulty when they find out a new baby is coming- but at 4yo they are old enough to know that hurting mommy or acting out is behavior that is not allowed! Talk with your child and sit down and establish rules with them. Its our jobs as mommys to set limits and boundries to stop unwanted, negative and dangerous behavior. Good luck !
