My 14 week old son sleeps brilliantly on my chest in bed, in anyones arms and in a bean bag on the sofa. He obviously likes to feel secure and snug but, how on earth do I make him feel safe in his crib? He will sleep for a maximum of 3 hours but gets very fretful when he wakes and doesn't like to be put down again. I've considered putting the beanbag inside the crib so that it cradles him but have my reservations about this. During the day, when he naps he sleeps on his front and is very content but obviously, this isn't advised for night time sleeping. Please can anyone offer any kind of advice?
