Why do children have longer REM cycles?

I read on the home page that children have longer REM cycles. Can anyone explain why this is ? Or how long their REM is compared to an adult?

vinny

Im not sure why this happens, but i think that infants and very small children have about 90% REM sleep per night. :)
