I was told to wake dd for feeds every 2.5-3 hrs the first weeks, then 3 hrs after that. Is he sleeping during the night the same?
Was he premature, jaundiced, low birth-weight?
Ok, I just saw in your title that he has days and nights confused. In that case, with exception for any medical circumstances, you should wake him for feeds during the day. This will help him to get more of his calories during the day, and help set his internal clock to a 12 hr day/night rather than a 24 hr day. Does that make sense?
