My older sister already has a 5 years old boy (which I love to death, his my first nephew and ill do anything to him). She is 4 years older than I am, she was a single mom, but she finally found a nice guy, she is so happy and we all adore him. She just told me she is pregnant and I was shocked and not excited or happy as I should be... I feel horrible for feeling this way? Why could it be? I mean I love her, we have always been close, but sometimes I can't stand her, I mean all siblings do the same I think. When she told me about my nephew I was super excited and happy, but this one was like.. I don't know I can't process the information and for some reason is like hard to see her go through that again... I can't picture her pregnant anymore and with a baby.
Notes: I am obviously younger, but I am married and a few months ago I lost a pregnancy... Could it be that?
Like I have always thought I would be pregnant with my first before her with her second. And honestly now, I will wait until the baby is born to start trying being pregnant again, because I do not want to be pregnant with her... I might sound mean but I don't.

Yes, you know the reasons, and you are right but its normal among siblings to feel that way, but you can choose you want to grow or be there, think mature she is your own sister, keep all the differences aside and be supportive in this time of her life, who knows if you get pregnant she can also be a great support for you , emotionally and physically. I understand after losing your own pregnancy one might feel how you are feeling (not very excited), but trust me, if someone else was pregnant rather than your sister, you would have felt the same for that person too. So don't feel horrible about yourself for feeling that way, its normal "Human Nature" . But know that the wise one will overcome that feeling by thinking in a way that that inborn child also a part of your family though its your sis baby, and love that baby as you love the first nephew. And as for your decision of not being pregnant at the same time while your sister is, its totally your decision. Have a great day.

Thanks Precious7.. you are totally right, I know eventually Ill be happy and excited, but now is like... blah! :/ Im sure it is like you said, it might be because if had a miscarriage and Im still hurt.
Thanks again! Have a fantastic day!

I am happy for you and your sis too.
And may God bless you with a wonderful cute little one. :)

Why or what rule is there, that you should be happy about it. It is another child for your sister, a nephew for you. In many families it is OK...

But you losing the pregnancy may cause emotions that are less than positive at this time

Yes, that might be it... Its just that I feel like a bad sister not being excited and happy as I should be.. like she calls me everyday to chat, and now obviously all she talks about is the pregnancy and having morning sickness and I get upset, instead of happy. I really think I feel this way for the miscarriage I had a few months ago. :(. Thanks for the answer!
