No "real live" brother or sister tonight

Taly is in tears presently because she doesn't have a "real live" brother or sister to sleep with in her room. This has become a bigger issue over the past year and seems to have come to a full boil tonight. Craig is trying to comfort her now, and I'm feeling like such a huge failure because I can't stay pregnant and now can't seem to even get pregnant. I desperately want a sibling for her and another child for us. I'm feeling like I just can't do anything right.
