For the past two week my 15 mo daughter has been fighting her afternoon nap. She has always been on the low end of A time and in the morning i can barely stretch past 2.5 hrs-usually she is awake for 2 hours before her first nap. Then she usually goes down pretty easily and sleeps for 1.5-2 hrs. Then 3 hours after she wakes up i try to put her down for a second nap and she does not fall asleep. Then the rest of the afternoon she is pretty cranky the rest of the day and i put her to sleep for the night by 6. Now she has also been waking really early for the day like 5:30! How can i stop this cycle and get her to take an afternoon nap?
