my 8 mth old is starting to wake 2 - 3 times at night again.... he had gotten into a pattern where he would sleep by 8:30pm and wake for 1 feed at 12 and then sleep until 7 or 8am. Now he is waking up at 11:30pm, 2am, 5am and 6am..... can anyone tell me why? its not for milk....i don;t know what is at the bottom of this and am completely confused and exhausted every morning. help!!
