I think the point Misty was trying to make was that we don't have to understand why people do certain things, but we do have to respect it. It is a very fine line indeed when talking about this sort of thing because there is no right or wrong, just different. I do what I do and you do what you do.
I think there is a certain element of smugness that accompanies these types of threads but we just have to accept that not everyone does things the same way as we do and of course that is going to make it seem like it is wrong just because we don't do it. I do things differently to a lot of people on here, but does that make me wrong to do it? Some of the people posting only have 1 child, so haven't yet had the experience of different children with different needs. It's pretty easy to comment that your way is the right way when you have only had to do it with one child kwim? I've got 4 kids, all with different personalities and different needs. I had one that self settled and slept through the night from an early age. I had one child that needed to be rocked to sleep. I had one that loathed being held to go to sleep, but would still cry in her cot for at least half an hour and then I had one that I had to co sleep with because of reflux. ALL of them challenged the way we parent them and often we had to use a wide variety of methods to make sure we were doing the right thing FOR THEM (however we never used CIO).
