Sleeping issues

Amanda

My 18 month old usually wakes around 7. Naps at 1230 wake about 130-2 and bedtime around 8. But the last few days she has been getting sleepy around 930am. I let her nap and she'll wake about 1030-1130. Since her wake window is about 5.5 hours that would make bedtime 530-6. This would mess with everything. Do I keep her awake until 8 or not let her nap early? What do you do?
