i am having a nightmare with my 18 month old. i wake her up at 8.00am, try to put her down for a nap an 12.30 but she does not fall asleep until 1'ish. i wake her up at 2.00pm - she is misrable because i woke her up. then put her in her cot at 8.00 but does not fall asleep till 9.00pm. I have tried to make her stay up all day but she always falls asleep at 4.00pm for half an hour which means she is awake until very late. please someone help me.
