If she's waking at 6 but wants to be back asleep by 7 I would treat that 6am waking as a NW as she is obviously not 'done' sleeping for the night at 6. Keep the room dark, no lights on, no milk, no chat, just try to settle her back to sleep.
10 months is a crazy time because they start to need longer As but still need 2 naps a day so it gets harder to fit the sleep into a 12 hr day. A 30-60 mins nap in the morning is OK, but you could try bringing her pm nap earlier so she has a shorter A time beforehand.
Teething does send everything out of whack too. You can try medicating 30 mins before her main nap to see if it will help her to sleep better.
