My DS is a little over one month old. He sleeps fairly well at night, usually having a 4-4.5 hour sleep, waking for a feed, then sleeping for another 3 hours. But during the day he just doesn't seem to want to sleep, or at least not for very long. He will fall asleep on me and I'll put him down in his bassinet, but it never lasts long - 15 minutes sometimes, an hour at most if I'm lucky. He generally doesn't act overtired, but I just thought that a newborn baby would sleep more than this. Is this normal, and is there anything I can do to get him to sleep for longer? Or do I just have a baby who doesn't need as much sleep?
