Hello and welcome
I think you're doing a great job! Some people are not able to give out of cage time to their gliders everyday. As Long as you interact with them on a daily basis, they seem happy, are healthy, and they are friendly towards you.... You're doing good. I only play with my babies through the cage if it's too late. Otherwise, if I allow them to be out during the late hours, it's almost impossible to get them back in their cage and when I do, they act really disappointed. Lol I will usually take mine out for extended playtime about an hour to an hour and a half before they usually get up for the night. I do 30-40 minute play sessions in the middle of the day (only if they're up for it). I have quite a few gliders though, so I have to balance spending time with everyone.
Anyway, you have to work around your schedule. I think you're doing a very good job though
