14 month old...how many hours of sleep??

Hi! My daughter is 14 months and usually sleeps great! The past week or two she wants to wake up at 6:15 am which seems like not enough sleep (just over 9 hours). She goes down at 9pm with no trouble and usually would wake around 7:45 am = almost 11 hours total of night time sleep which seems to be what I have found as normal on some websites. She sleeps through the night. Any reason for this random and abrupt switch for wake up time? She gets two naps in the day time which, with her old sleep schedule, would equal about 14 hours of sleep total. Now with her waking up more than an hour earlier she's obviously getting less sleep and seems more cranky. She is teething and has gotten 2 molars recently so I'm wondering if that could be why and she will revert back to her old sleep schedule. Anyone else dealing with this right now? How many hours are your babies her age sleeping? I hate to think of how early she would be waking if she went down at 7 or 8 pm.
