Sleep Training.

I am a mom with internet access. I am on a board and I talk with my friends via facebook, and something that comes up a lot is Sleep Training. I believe that it is absolutely ridiculous to sleep train before a year, unless (yes unless) you work full time or part time in the mornings. Let your child grow without interfering with how your child sleeps.
I have heard (please do not flame me if not true) that Crying It Out can actually be harmful for a baby's brain (emotional) development. Why would I do this to my son?? Although we do bed-share, we put our son in his PnP at first, we found he sleeps longer this way and then we bring him into our bed for the rest of the night. He usually gets a good stretch of sleep in before he wakes up. Although he did sleep better right after we brought him home, which I was thankful for for my recovery.
I feel like I need to post a disclosure: I believe in natural parenting. Let the child lead. Feed on demand, no CIO (I do nurse to sleep), babywear, cloth diaper, EBF. I know that not all families can live this way, but I believe that those who can, should. Also please save Sleep Training till at least 6 months, I know they can say you can start at 3 (and sadly I know people who have started with newborns). Give your baby some time to grow and develop before you start.
