The time frame for bonding can take anywhere from immediately to a few months. One thing I found that helps is to carry your new pet around in a shirt pocket all day. During the day you can pet and bond with your Sugar Glider even if he is asleep. He will get used to your scent and touch at the same time. If you do carry him in your shirt pocket be careful not to lean against anything that could possibly injure your pet.
Sugar Gliders tend to bond closer to their main caretaker.
They can and will accept other people but tend to stay with their main handler. Mine have allowed me to hand them over to someone else and as soon as I started walking away, they jumped right back to me. They seem to be able to sense how I'm feeling. When I have been upset, they tend to stay in my shirt more than normal, occasionally coming out to get me to play. When I'm sad, they come up and tend to want to love on me and let me pet them more.
