hi...we had homebirths w/both our kids and used water both times. We actually did use the kiddie pool and loved it. THough granted you do have to do some work to keep it hot. neither child was born in the water but had circumstances permitted, I believe that is what woulda happened. However, I do hear that many woman like to labor in water but feel like getting out to push. The gravity and all.
there is a thread on this site re: siblings and videos for them to watch you might want to check out. We just watched "gentle birth choices" and I thought it was pretty good. My all time fave is "a clear road to birth" which is actually a freebirth(unassisted) video. has awesome peaceful births w/mama catching her own babies. there is also supposedly (friend recommended but never got my hands on it) a wonderful waterbirth video called something like water....oh I don't remember exactly but it is about the russians who did a ton of them. I remember they sell it on www.midwiferytoday.com
cuz I was planning on buying it.
as for books...hmmm...there are so many good ones. try Jeannine Parvati Baker books, special delivery by rahima baldwin, can't think of any thing else right now.
anyway...good luck. happy planning
