ok, just so all the info is in one spot ...
you followed Bourbons bml recipe
http://www.bmldiet.com/bml-recipe.html
if it were me I'd try putting it all in one bowl and layering it. Fruit in the bottom then veg then staple (bml) on top so as it melts it coats the veg and fruit and her fav is at the bottom. This way she will get some of the bml even if its just from cleaning it off her hands.
you can also try icing the bml, "ICE" the BML mix with applesauce or another fruit, then reduce the amounts of cut fruit offered. By icing you take about 1/8 teaspoon of applesauce and spread it across the top of the BML mix. Take the edge of a spoon and cut ridges into the BML mix.
**Put the food in the cage about a half hour before she wakes up and remove the plate after she goes to bed in the morning
**They only eat the insides of the corn, peas and green beans, at first glance it may look untouched, closer inspection may reveal they are eating more than you think.
A lot of things can affect gliders eating, some of them are...
Age- younger gliders grow into eating fruits and veg. But at 2 yrs old your girl is well passed that.
weather- storms coming and going, barometric pressure changes, change in season, temp changes etc... can all affect eating habits for a few days.
females in heat- can reduce appetites but also just for a few days.
Treats- to many treats or drinks during the day or right before dinner time. My treat cut off time is about 1 pm unless I'm trimming nails that day. I only do mealworms for treats when I trim nails or if i have to give medicine they might get one after their dose.
Environment changes this can be almost anything from lights being left on, room temp change, changing toys in cage, changing cage, moving cage....
moon phase may seem weird but very true
how long have you had her and what was she eating before?
