I'm a first-timer and have no clue... I've come across this a few times now in some of the books that I have been reading (but not all of them) and was wondering what your experiences are? Is it better for baby's sleep patterns to be in a completely dark room? Or is it maybe more of an issue in spring/summer, when the sun rises early?
And if you do get them used to a completely dark room, does that then mean they can't sleep anywhere else? We do expect to do a fair amount of travelling with baby, so would I have to take these travel black-out curtains everywhere we go?
