Hello! I'm not a frequent poster but I am a member.
Congratulations on your new babies! I remember when we got our boys, my two daughters were SO excited to get them but when we got them all they did was hide from us and crab at us if we came anywhere near them. We left them alone for a good four days before I even tried to handle them. It's soooo important to let them bond with you on their own terms. On the fourth day I brought their pouch into the bathroom with me late at night and let them hop around on me while I played on the computer or read a book. I made no attempt to catch them or hold them, I just let them jump around and get to know my smell. after a few days of this they actually sought me out and enjoyed the attention I gave them (Petting, sweet licky treats from my finger and talking to them).
About the biting, I know it's intimidating but you need to take the bite. Do not be scared of holding them or handling them. They can tell if you are nervous and they may in turn get scared of you. Try to be calm, do not yelp or shout if they scratch you or nip at you.
We have had our boys for 6 months and we LOVE them!!! They are the most loving, cuddly, sweet little guys you can imagine. We give them lots of attention in the early morning and late at night, we give them lots of snuggles during the day while they are sleeping. It takes patience to bond with sugar gliders but it's SO worth it! It's so cute when they come running to you when they get a little nervous.
oh and one more thing, do not seperate your gilders, they are bonded, they need eachother. If one if a boy you need to get him fixed.
