ATTENTION SUGAR GLIDER OWNERS!?

my sugar glider is sleeping and waking at weird times. they are supposed to wake up around 9 pm and go back to sleep at 5 am or 6 am. but my sugar glider wakes up at 12 midnight and goes to sleep at 10 in the afternoon. sometimes, she even wakes up at 2 am and goes to sleep at 5 am. what is wrong with her? she is well fed, has her daily vitamins and calcium, eats meal worms, so she has protein. her food is fine, cage is clean, and everything that she needs she has. any ideas as to what is wrong? any solutions???
