It's not easy. SIL was pg when I had my first miscarriage, due dates 3 months apart. I had to be tough. I didn't want her to feel like they needed to shy away from me and made it very clear from the start how I felt. There were a few instances where it was particularly difficult, mostly due to her being insensitive. I was really worried that when my niece was born, I'd really feel if, but it was okay. I don't know how or why I got through, I guess I figured I just had to.
