I couldve given birth at home, on my own, with no one there to help me. Some women are actually going back to doing that now. Even so, they would still prepare. I personally never would do it though
. I could've never gotten any prenatel care at all, and my kids could've came out fine, but that wouldnt have been wise.
Sure mama is going to do most (if not all) of the work, but you do need to be prepared and you do need to be informed of what will happen and what COULD happen. Dogs have been doing this just as long as people, and they do it in the wild, but why tempt fate?
