Exactly. Do these people who are convinced they are right all the time actual parent all of their children in the exact same way?? I sure don't. My oldest did not ever sleep with us. Maybe she would have slept better if she had, but you do what you think is best at the time.

We did the Ferber method with the oldest two but not the youngest. He was always put to bed awake and never had issues in the middle of the night either. Middle DS OTOH went to bed just fine and then believed that he should be rocked to sleep and held all night long when we was about 8 months old. Two nights of crying and he stopped doing that.
Oh, and BTW, we always left the heat on so his room was never cold and dark.
