Did you get the regular Repashy food? Sometimes it takes them a little while to get used to it because if I remember correctly they changed something about the food that made it taste different and it wasn't a big hit but most Crestie's still gobble it up. They have different flavors other than the regular also.
You can mix a tiny bit of peach or mango baby food in with the Repashy, and then once they start eating it, you wean them off the baby food.
Most of the time my babies were pooping every day or every other day.
I put a very small amount of CGD in their bowls because then I would know if they were eating it because there would be tongue marks in it
I never froze mine, just made it every night and fed them, because they don't eat a lot. Maybe a couple licks a night.
I never fed fruits, Crestie's can live fine on just protein. Having them on only CGD will keep them healthy, they will just grow a lot slower. When I had my two babies, one didn't like bugs and the other was a bug loving fiend. They were the same age but the one who ate bugs was double the size of the one who didn't like them after a couple months.
