Can you leave other sugar gliders in with baby sugar gliders?

The parents of the sugar glider should stay with the baby for at least 8 weeks, if that is what you're asking.

In their natural state, sugar gliders may live in a group of up to seven adults and their young, which form a 'clan', sharing a nest. The young joeys learn to socialise with the other young, playing with them, but also learn to be fiercely defensive of their own territory. Whether this works when sugar gliders are being kept in captivity in a tiny cage is uncertain.
