It is almost always going to happen. After you went through a difficult pregnancy, experienced a loss, a mom will find herself pregnant again.
It is very worrysome, and trying for the mom to be. It is aslo hard for the dad to be as well.
The fears come back with vengeance. Many people will say to you, "Well, I am just so happy that you are finally over the loss." And you realize, people still don't get it. It's not that you have finally gotten over the pain of losing your child. Time just moved on. I mean your not supposed to all of a sudden stop living you life.
It's been 2 years since I lost the boys, and not a day goes by without thinking of them. Same if my child was on a trip w/ the grandparents, I would still think of her. Out of sight does not mean out of mind.
A new baby will and can never replace the lost baby. No two people are the same, even siblings.
You have heard me say this, talk through it. tell your fears letting out your emotions will help. you will learn so much of you and your self, but people will begin to learn more about you. And if they don't then they aren't who you thought they where.
