So when I got my babies about a month ago they were waking up around 9pm and staying up until 9am. They are eating all there food and I also took them to the vet when I got them and she said they were healthy babies. But they are now starting to wake up around 1 or 2am and going to sleep around 1 or 2 in the afternoon.. to make sure they are eating I've been putting the food out later because they wont come out of there pouch when I try to wake them. They don't look sick there ears are perky and they dont look lethargic and they are still eating all there food. what do I do?

Are you keeping the lights on later, they could be just not coming out because it is bright in the room and they think it is still daytime.

Try dimming the lights early in the evening and see if they go back to their regular time.
