My 3 month old son sleeps well at night but is constantly tired during the day. Sometimes he's awake no longer than half an hour and he's rubbing his eyes, yawning and very cranky. Problem is, he has to be coerced into taking his naps, which last no longer than 45 minutes. It's getting to the stage where we have no quality time as it's a constant battle to get him to nap. I've tried taking him out in the pram, introducing a dummy, feeding him, cuddling him, rocking in the moses basket but nothing will induce a long restorative sleep. He used to have to be roused from his lunchtime nap after 2 hours but since about week 9 he's just a right cranky pants and I'm exhausted. He's had a cold for a week so that may be making things worse but I'm at a loss to know what to do.
