Congrats on your new baby.
I'm going to go against the stream here and tell you it's ok if you don't have the time to spend with her that you used to. There are many people that don't do out of cage time, or bonding bag time with their gliders. There are many gliders that do just fine on their own too.
Breathe. It's ok. Your doing the best you can for her and believe me it's probably more than most people are able to do.
Personally I have 8 gliders now, I rarely do "out of cage time" because I don't need to. Their cages are set up with toys, wheels, food, all the things they want and need. When I DO do out of cage time, it lasts about 20 minutes if I'm any where near their cages. After 20 minutes... they all voluntarily go back to their cage, go inside, get a drink and go back into their pouches. They love their cages, it has all their fav stuff in them.
I do a morning check on everyone, and dish out treats, but they don't always come out of the cage or spend time on me like they used to. It's harder to do with 8. There are days I can manage to get them all out for a couple hours in a day but usually I rotate cages through the week. I get one cage out for the day then the next day or day after it's the next cage and so on.
this last march i had to go to Ny for the birth of my grand daughter. I was gone 5 weeks. My boyfriend tended to the gliders but didn't get them out the entire time I was gone. When I got home, they were all just fine and we got back on MY normal routine... life happens, we get busy, and the gliders will adjust to new schedules and routines.
I understand your concern is because she is a solo glider now, but the same applies to them. If you have a wheel and some toys and can keep her cage interesting she will be just fine until your routine levels out and gets on more regular schedule.
30-45 minutes a day is more than most people can manage and is more than enough and she can probably tolerate skipping a day or two if need be.
I can not tell you what is best for her, and what you should do. But I am saying a few months of getting a new routine established and life getting busy is quite normal and in the grand scheme of things is really not that long for a glider.
Is it going to tug on your heart a lil? probably. We all go through that at some point or another. The glider community puts some pretty high expectations on glider owners, and it can make us feel guilty if we don't meet those standards.
Make her cage interesting, with a glider safe wheel, and a bonding buddy to give her something to cuddle ( they are made of fleece and small and can go in the sleep pouch so they don't feel alone ) change or add new toys to give her some stimulation.... there are many things you can do to occupy her even if you have to reduce the time you can spend with her for a while.
