I'm not complaining but my newborn who is coming up to three weeks has slept a lot of the day. Unless I wake him for a feed/nappy change he will sleep. Is this normal? He's got normal nappies, temperature is fine etc. he's also alert when awake..... he just doesn't seem to do much. My parents say he's a good baby and content etc.... I wake him for feeds every 3 hours during the day and 4 hours at night.... trying to stretch it out.
