Ahh, I know what you mean - Twins born apart. We have 10 frozen embryos, which have been frozen for 2 years now. We will most likely end up using them for our next bub. Its weird knowing they were sort of conceived so to speak 2 years ago. On my birthday actually!!!! I am glad to hear your sister had success. I found the jouney wasnt emotional until after I had DS, as it wasnt until then that i realised what i could have missed out on. I do really feel for people who cant have children. I wouldnt feel complete without them.
