The yogurt-in-a-crock-pot method works great! I left the crock pot wrapped up in towels out overnight, leaving it out unintentionally 8 hours longer than suggested in the directions. It didn't matter at all (I didn't think it would but I thought we'd end up with tarter yogurt). The yogurt is still pleasantly mild and it set up beautifully.
Pregnancy leg cramps have begun. I woke up in agony from the worst calf cramp ever. It's amazing that a muscle cramp can be so painful. Week 25 is a little later than cramping started with the other two I think, so I guess that's positive. Most of the cramping I had with my other two pregnancies were hip cramps. I don't think I have a preference on the location--none would be nice.
