Sleep help pleas

Jess

My sweet angel has all of a sudden stopped sleeping good at all. She goes to bed about 6:30ish that is becoming a little bit of a fight. She wakes up around 12:30 is up until 2am and is just up. Happy as can be just wanting to play. Then back up at 5am. We are exhausted at this point, please help. She also takes two 30-40 min naps during the day.

Pic because she is adorable.
