Winter Fasts?

[200xth]

I weigh her semi-regularly ... how often should I be weighing her would you say? Last time i weighed her was October 28th

I, pesonally, would say start with every 2 weeks or every month, but everyone will have their own ideas about this. You just want it often enough to be able to see if there's an issue. If she goes on a 6 month fast you'll feel better being able to look back and see that after 6 months of no food she's only lost a trivial amount of weight.
