Hi G.,
You are not alone my dear, and your son's reaction to the baby VERY NORMAL!
My Daughter is 4 1/2 yrs. older than my son. She prayed for a sibling and was so excited that I was finally pregnant. I even took her to the store to pick out a gift for her Baby Brother for her to give to him the first time Daddy brought her to the hospital. I also had a very special gift for her from her Baby Brother (something she really wanted and to this day she still remembers what that was). I had it all planned and of course had to remember to bring the gift with me to the hospital to have it ready when she came to visit Mommy and Baby. She of course, was excited and wanted to hold him etc..
However, that all changed when we got home and the novelty of Baby Brother wore off and reality set in. Her world went upside down quickly and she plain got angry. My mother in law came to help for a couple days and had to have a talk with me to say that my daughter had asked when we were going to finally take him back to the hospital!! I truly hurt for her and put myself in her shoes. Plus as new moms were still pretty emotional with the hormones and all. I cried but then my husband and I just really made it a point to spend even more time (when I was not nursing)with her and truly make it quality time. Plus make sure and talk and reassure her of our love and the changes that were occuring but that it would get better and soon she would be able to play with him. In retrospect I think the only thing I would of changed was to make her more a part of me nursing. But I wanted to be modest because It was difficult nursing both of my children. I was never one of those Moms that could nurse comfortably in public. They would distract very easily so I primarily did it in a quiet place alone.
Another difficulty for her to understand was that she wanted a playmate not a Baby. I tried to always make her a part and be a helper to Mommy. I would also say "Mommy does not know how she would do it without all her help"!
Well, they are now 10 and 5 yrs. old and truly are the best of buds and truly love eachother. My daughter looks out for him and sometimes can mother too much. My son worships the ground his Sissy walks on.
So hang in there. This too will pass.........
Enjoy them both!
