DS 5 months can self settle well after his 7pm bedtime routine (bath, bottle, story) and can wait happily in his cot until he falls asleep. Daytimes could not be more different. He screams bloody murder if left in his cot, no matter how tired he is. I'm getting into the dangerous habit of taking him out for a walk or in the car for every nap! Why can't he settle himself in the day like he can at bed time?!
