I understand about babies' sleep cycles and waking after each cycle, so my question isn't really about that. I want to know why babies can't even sleep that long.
When I finally get my son to sleep (which takes hours) he will wake up ten minutes later. Twenty if I'm lucky. He occasionally sleeps for an hour which I presume is a full cycle but mainly it's 20 mins or so. Day and night.
I'm shattered. Help.
