My baby is 8 weeks and at night he won't settle in his cot before midnight but he will doze off in the bouncer chair in the living room. Then at midnight he goes into the cot and sleeps for 5 hours, has a feed then goes back into cot for another 2/3 hours. So why won't he settle in the cot around 8 or 9pm? Cos he does get tired around then but seems to prefer dozing in his chair in the living room instead. Any thoughts?
