Xvart, I've never witnessed a glider birth before, so I'm really not sure. All I know is that she does it alone and the daddy just watches,lol, kind of just stays out of the way. It can happen at any time of day, they're nocturnal but she can still give birth in the day. She will have some contractions before the birth so I'll look for that. She actually won't help the babies at all when it comes to them getting into her pouch, the babies have to climb on their own up and find the pouch, then get in it and find a nipple which they will be latched onto for 2 whole months, this will be a very critical time because the babies are blind and deaf still at this point, so hopefully they will make it alright by themselves, if I notice that one has fallen then I can place it back onto the mommy's tummy, near her pouch and hopefully it will be ok then, if not I will have to try and hand raise it myself. When the babies come out of the pouch approx. 70 days later, then the daddy will help, he's not useless throughout the whole thing,lol. He will carry the babies on his back and bring them food as well, as will the mom.
Nep-ak, If she got pregnant on the day that I saw them mating (December,10th) then they should be born on or around December-26th, then they will come out of the pouch for good around March-7th of next year, loooong time! But since they're only in the mom's belly for 16 days, they have to do the rest of the growing in the pouch. I hope I'm right about her being pregnant, we're really excited!
