My 9 week old son wont sleep during the day, feeds every 30 minutes and cries for most of the time he's awake. I've tried rocking him to sleep which doesn't work at all, feeding him to sleep, lasts 20 minutes max, taking him out in the car - only lasts as long as the cars moving and finally, leaving him in his cot to see if he'll go to sleep on his own. I'm running out of ideas!!!
