"It seems to me people make the mistake of thinking of their children as little people too much.
Babies do not think and feel the same way that adults or even small children do, they are entirely selfish and have no comprehension of time."
So if not little people, what on earth are they?
And what nuisances they are to selfishly expect to have their needs met at inconvenient times....
I have never done CC for any of my DCs (5 in all, 11 years from the birth of DC1 to the birth of DC5) and all are exceptional sleepers. They all slept really badly for the first year or so; one didn't sleep through until she was at least 2.5. I always expected sleep deprivation to be part of the picture with babies and trained myself not to be so attached to the tv or my own amusement while they were younger.
I have as much proof of the non-CC route being a part of their present niceness and good sleeping habits as anyone here who has done CC and had similar results does. It's all just a wild stab in the dark, with 'it works' offered as the justification. Hardly scientific.
Here's an article on sleep cycles of infants. An alternative to CC or co-sleeping if it's not for you may be swaddling, which has some benefits sleepwise.
Flight, I agree with you about the order of how needs are met -- older and presumably more mature and patient people can be expected to wait, and do some of the attending to their needs themselves. Mum is not there to cater to all of the people all of the time. As far as I'm concerned, a baby has a bigger claim to my attention than anything else for as long as it takes.
