I have a one year old who up until now had been a dream sleeper. She was in a pretty straightforward routine of two naps a day, then she dropped her arvo nap and that's when the issues began. I feel like she needs that arvo nap because by bedtime she is exhausted but she just screams and stands up in her cot if I try to put her down in the arvo. Now she's so overtired by bedtime that she screams and cries for an hour before finally falling asleep. I need your advice please, not sure how to handle this one.
