She has her days and nights confused. It will take a couple days and nights to get her internal clock set with our clocks, but it will be important to be consistent with sleeping and waking times.
At this age, a child's sleep cycle is 90 minutes. This means they need at least 90 minute intervals of sleep for it to gve them any benefit.
She is probably over-tired too. Getting her on a schedule similar to the following is the one my experience has shown to be most successful:
Wake up somewhere between 6-8
Breakfast
Morning nap beginning between 9-10 and lasting 90 minutes
Lunch around 12:00
Afternoon nap beginning somewhere between 1-2 and and lasting at least 90 minutes, but make sure she is awake by 4/4:30
Dinner around 6
Bath and Bed somewhere between 7-8
Routine is important! Set up cues to signal that it is nap/bed time (ex: a specific book, cuddle time, darkness, soft music,etc).
The most important, and hardest thing is going to be ignoring her throughout the night if she wakes up. It can be hard to listen to her cry, but if you run to her, pick her up, let her play or put her in your bed the behavior is only being reinforced.
Good Luck!
