Interested to know others views as I always put DS in the dark for his daytime sleeps as i had read this would help him sleep at night. Now have DD 7 weeks do n't think she has ever gone to sleep during the day in the dark as we are usually out. Does'nt seem to have made any difference still goes down at 7-730 in the dark and sleeps to 2 then again till 6, have recently read that daytime naps should n't be in the dark as they need to learn the difference between night and day what do others think?
