Hi * Sophie*. I think you are jealous and understandably so. It's not fair that you can do everything possible to have a healthy pregnancy and miscarry several times, whilst others do everything wrong and have healthy babies in the worst circumstances. To have that multiple times over in your own family must be a real kick in the teeth. Don't know if it helps but someone said to me when I was struggling with jealous feelings to think if you'd want to swap lives with the person you are jealous of... sounds like your step-sibs are going to be in pretty miserable circumstances. The other thing is they are not having your baby, just a baby. Your baby is still out there waiting for the right time to come to you. (hope that's not too "woo") You have my sympathy, it's going to be tough watching them all.
