Just an FYI...when gliders give birth to joeys, they are about the size of a grain of rice. Then, they crawl into the pouch, latch on to a nipple and that's where they develop for the next 10 weeks. Your joey was actually born over 2 1/2 months ago. You'll hear people refer to joeys being "OOP" (Out of Pouch). Basically, today's your joey's first day OOP.
