We have 2 baby suggies for about 45 days. We have them on the TPG diet (make food at home and freeze) but I feel like they are just licking the juice and may not be getting all the nutrients they need. Does anyone have any advice? Is Glide R Chow better???

You should be fine with the TPG diet. If you're concerned about them getting the nutrients they need then watch the condition of their fur and weigh them. They should be gaining weight steadily and the fur wants to maintain a healthy fluffy look.

"Either finely chop or use a food processor."

that is the instructions for the TPG diet for veggies. My wife and I did this
diet for a few times and this is the issue we had, the gliders eat the inside of
the pea and throw away the outside shell, the gliders eat the inside of the green
been and throw away the outside, but if you food processor it how can they NOT
eat some parts.
DON'T GET ME WRONG, I'm NOT saying its a bad diet, just some of the stuff we
read says not to cut up veggies.

The critterlove complete (instant) seemed a LOT less complicated for new glider
owners, then once we had it down, we switched to the critterlove PLUS.
Glide R grave is critterlove complete JUST i think more expensive so the other
seller can make some $$, if you wish to switch just buy from critterlove.com.
Glider R Chow is Happy glider food @ pet-pro.com I think pet-pro is also cheaper, but chow is a great healthy snack I keep in cage, good at cleaning teeth,
but NOT considered by many a complete meal. Freeze the unused bag in freezer, over time it can go bad.

the weight check from paani is a great idea. gliders also suck out the juice
from food and spit out a half moon solid leftover uneaten part. they get it ALL
OVER my food kitchen.

In the end I think both diets are probably healthy.
BML is also considered a good healthy diet.
