Any advice?

I am just pregnant...10wks...and my niece, who is 15 has just found out about 5 wks ago.  She has always been my baby.  She lives with my momma basically because her dad and mom just could not be parents(and still cannot be).  :(

Ever since she has found out I am pregnant, she has been so freakin' mean and hateful to me.  I know its because she thinks this baby will take all of my love, but dang, I have enough for her and this baby.  But she is making it hard to be around her, and truthfully, making her very hard to love right now.

Downright hateful to the point where she said that she hopes that my baby dies.  :(
She eventually apologized, but everytime she gets mad, she'll say it again.

What would you do with your niece besides kill her?  These hormones are making me less than patient with her.

I had similar issues with my niece and nephew, but there were 7 and 3 at the time. I am very attached with them and spoiled them and spent as much time as I could with them. They are my brothers children and we are close. We actually had our homes built back to back. They were always over here or vice versa and going out with me, etc. When I found out I was pregnant, my niece, Emily, became the same way. Spiteful. She felt jealous and threatened. I tried to really make her feel that the arrival of a new baby would not replace my love for her. I tried to involve her as much as I could....doing the room, shopping, naming the baby...you name it.  After my son arrived at first it was hard and the jealousy did rear its head again. It was hard for her because I could not just go out shopping, play a game, etc. But again, tried to involve her as much as I could and at least once a week set aside time where we could be together, just me and her, no baby...talk, paint nails, cook, etc That helped a lot. Your niece is older, so I would recommend just sitting down with her and hashing out feelings. Set expectations, make no promises....you cant be for sure the baby wont take all your time at first but once you get a routine down it will help. Offer for her to help now and after baby comes and lots of reassurance. Hope that helps some.

Tell her she will driving, dating, and possibly working by the time the baby is six months old.  She won't have time for you, so you had to have a baby lol.
