I did a bit of sleep stuff with DS1 and i disliked it. He currently sleeps like a trooper and rarely wakes. He's 4.5. He will sleep in new places, new beds, from 7-7.30 - 5.50

I did nothing with DS2. He slept through the night for the first time when he was about 18 months. He is now in a big bed and gets put to bed, half the time falls asleep within 5 minutes the other half he calls out for me a few times. He wakes one or two times most nights and often wakes up tired, ITMS.

They are very different children. I think the sleep thing has to do with their personalities. I do also think ('cos i'm an expert LOL) that children can learn to 'cope' with less sleep. They get used to it. It might not be good for them, or ideal, but they learn to function. I know a child who seems sleep deprived and is not given the opportunities to sleep that i think are more healthy. He's 4.5 now and can function on the same amount of sleep as me. I think it would take a lot of work/training to get him to sleep for longer now. It's like he's been sleep trained in to less sleep.
