I was actually just going to post about this too! I've been feeling a definite sensation - like that early fluttery feeling - the past few days that I've only ever felt during pregnancy before. If someone else had told me they were feeling the baby this early I would not have believed them, but I have no doubt that I am feeling baby in some way. It's so reassuring, isn't it?
Best wishes that the natural childbirth process goes well for you! Me, I'm going for the drugs but I think anyone who can do this is simply awesome!
