Youngspiritmom- When I was going to school full-time, we were planning on having about 4.5 years between children so I could finish school first. It was longer than we wanted, but still reasonable and I thought it would be worth it to finish school before adding to our family. Then I decided that it was too hard to go to school full-time with a toddler, so now that I'm going part-time we're not willing to wait that long to have another. It's difficult to go to school even part-time with a child, but it's doable.
Mulvah- I definitely suggest buying a half-cow and storing it in your freezer. When we bought our half pig (I haven't done it yet for the half cow we just got), it ended up being about the same price as buying meat at the store (not on sale, just regular price). It sucks to drop 1000 on a cow all at once and you have to factor in the freezer, but this meat is SO much better than the quality you get at the store and better for you. I don't feel at all guilty about feeding it to my daughter. Plus you get all different cuts of meat, so you learn to cook different cuts and you get nice ones that you may not buy in the store because of the price.
