My ds is 9 months old and is refusing to go to sleep until like 11:30ish at night then wakes up at like 2 and stays awake until 4-5 and will not nurse!! He will nurse during the day and nurse to nap but come night time he just cries. It seems like he is avoiding nursing so he wont go to sleep. I want him to go to sleep at a reasonable hour, like 8 or 9 and i just want to know why he is doing this? Thank you guys, you are wonderful!!
