As a dad in nominal charge of sleeptime, I need help. None of our three DSs is a good sleeper (my genes) but DS3 aged 2 takes the biscuit. Perhaps because we didn't do the controlled crying regime that we did with DS1 and DS2 one of us has to stay in DS3's room until he goes to sleep, often as late as 9pm. If we leave him awake he can happily vault out of his cot and walk downstairs. He is cute as chips but we'd rather he went to asleep before the watershed . Any advice?
