HI, DS is a cat napper, i wish he wasnt , as he wakes up so cranky,, so i am off to sleep school to get help.. if he woke up happy , it wouldnt worry me, if he cat napped all day. but he is so sad and unhappy when he is awake and tired.. i can only dream that he would sleep a minmum of 1.5hrs at a time duroing day sleeps
