Just received three gliders, breeding pair and baby(6 wks oop) . The male and baby are the nicest I've ever had. Mom is a different story. She crabs every time I try to touch their pouch. I thought I got her to trust me when she licked apple sauce from my finger then she but me. I thought it was only because there wasn't much left on my finger so I got more and she bit again hard. Not enough to break my skin but hard enough for me to wince. Now every time I giver her apple sauce he bites no matter what. I haven't even gotten to hold her yet every time a go near her she lunges at me and bites. Any ideas to help?
