At your DD's age my DD was still having 2 sleeps a day, morning and afternoon. She would be in bed by 7pm and usually awake fairly early for a bf. She would then sleep in bed with us until around 6:30-7am.

She dropped the morning nap by about 16 mths from memory, bed time hasn't changed until recently (7:30pm as she has dinner with us now). Thankfully the morning bf started to get later from about 18 mths, not before 6am usually.
