this sounds fantastic! your baby must be so happy to have a glider friend:)
as for your new one, he will be much more comfortable with you once he is with your previous glider. he will soon understand that you are a friend and mean no harm. plus you give out free treats!
when I got my new glider as a companion for my current one, she was mean, scared, and loved to crab. once I introduced her to my bonded glider, she turned into a new glider. she is now even more loving than my first one. during bathroom bonding she usually wants to hang around on my shoulder or on my head grooming me while my other glider hops around and explores while coming back to "check" on me every so often.
