I always wanted to do a long term study on how parents put kids to sleep. I have two insomniac relatives, both parents rocked their kids to sleep till they were to big to fit in the chair. I always wondered if there was a correlation. I also always wanted to ask if their siblings are just as insomnic, and if so is that genetic or cause all were rocked to sleep?
But the likely hood of being able to find a parent who HONESTLY remembers what they did to get their kid to sleep say 20 years ago is pretty low. That and the likelyhood of icluding all THREE methods CIO, rock them, and gradual walk out, are pretty small in a major funded sleep study. You know the kind that can actually get a couple hundred parents and follow the kids for 20 years. (I btw have no idea how I was put to sleep, with my children I used the gradual 'fade out')
Another thing I think would be cool is to compare the statistics of Hoime Educated kids and Public Schooled kids and Private Schooled kids. I happen to prefer Home Educating, but then I was also a teacher (disclaimer, no degree) What about all the parents that do not have a telant for teaching? is private school really as good? I personally can't see how traditional Mass, Age based Education can be. But then not all private schools are Age based or Mass. ('course I also think teaching is a skill that is losing ground while more and more people are told they cannot do it and shouldn't try) Oh I guess a disclamer, yes I have seen many different studies comparing Age based, Mass education and Home Education and statistically Home Educating comes out ahead, on IQs, test scores, and adult 'life satisfaction' (which is the most important of the three IMO)
Oh one last silly pet project. The lie of Santa claus in Christian families. I personally don't lie period, but I always wondered if the belief in the unseen is proven shaken. (lied about santa, lied about easter bunny, yet I am supposed to believe in Jesus?)
