Amen re statistics! Sandy Breck of U of Mich. is really good at that sort of stuff. I'm hopeless at reading stats - I like percentages and things that say "statistically signficant" (or not) and hope they are telling the truth. No, I'm a bit better than that, but you're right, we need to look at all the data. I still think James McKenna's stuff on co-sleeping is outstanding. For those of you that are not familiar with him, he gave a wonderful talk at ILCA last year - his tapes are still available through First Tape, Inc. in Chicago. I think you can get the address out of the JHL. Jan
