I agree that every situation is different. If you can let them nurse, great!
Vee will be weaned around 4-4 1/2 months because Mom is old and having a harder time keeping up, so for her it is the best choice to make. Baby is already eating hay and grain out of Mom's dish so we think she will handle it well. She will not be "pumped full of grain" or pressured to grow, it is just the situation at hand, which is why I'm trying to plan the best feeds for her (relative to my area) so that she can grow up having the right start.
