Hi J.:
You recieved a few good responses,but I thought I'd give it an answer on a childs perspective.First of all,your daughter is not jealous of her new brother.She adores her new brother,and loves the idea of having A sibling to have fun with.She however feels a little confused. She liked the whole (baby idea),until she witnessed mommy,daddy and all their friends making over the new arival. She just didn't know it involved sharing so much of you and daddy! shes probably tossing it around,as to wether she wants to send him back to the store you bought him from. lol She probably watches you,and how you cuddle him and baby him....Much like you did her,not to long ago.You no doubt prepared her for the new baby,months in advance. Telling her,that she would be the big sister. He would be a tiny baby,and she would be A (big girl)So, the baby comes,and she attempts to be the (big girl)You tell her what she is wearing,when and what she is eating,when to pick up her toys,when its time for her to take a bath and What time she must get dressed for bed. When she tries to play her new given role as the big sister,she is told (No) or you can't or you must,or I want you to or now! Shes no longer the baby,but shes not the big sister either,because she is given no choices.You need to allow her to make some. Don't make everything a struggle,or battle of the minds.Give her some room to grow,and get to know her particular place in the family now.Punishing her for unsuccessfuly expressing her feelings,is not going to benifit her or you. Putting her in a room,separating her physically from you,will create more hurt feelings,and that of alienation.Its simply going to create more confusion for her."Mommy only wants to be with the baby" "I don't make mommy happy" "She doesn't want to be with me. No Child should feel,that they are only loved,when they are good.That we only want to be with them,when they are on their best behavior.They need to know,they are loved,unconditionaly. They quickly learn the meaning of compassion,and forgiveness,when their parent shows understanding and exceptance,for mistakes they have made.My advice would be to include her more,when it comes to caring for her brother,and set special time aside for her,so she can remain feeling special.Remember,she may appear to busy at play or even run, kick and fuss,but she wants you to catch her,and hug her. She hasn't forgotten so soon,how special you made her feel.She just needs to be reminded from time to time. Soon,she will adjust, feel more secure,and she and her new brother,will be the best buddies ever.I wish you all the best.
