The Ultimate Baby Insomnia?

New Scientist is carrying this report on a remarkable discovery about dolphins and killer whales... both newborns and their mothers don't sleep at all for at least the first month after birth. Stranger still, tests showed the animals did not seem to be stressed at all by this activity. Considering some mammals will die if deprived sleep (and most human parents slowly lose their marbles over a newborn's inability to sleep any real length of time), this unexpected adaptation is quite mysterious indeed.
