He is eating a mash made primarily of Zoo Med box turtle food. Into the mash I put, on a rotating basis, a variety of fresh fruits and veggies, along with a little bit of protein baby food (which by the way, has convinced me that I should never have a baby- I am not sure I could stand smelling that stuff for the 30 minutes a day it might take to feed the kid).
I've included veggies like collard greens, winter squash, yellow squash, sweet potato, apple sauce, pears, strawberries, tomatos, blueberries, raspberries, and bananas. I usually throw some worms (red wiggler, super or mealy) on top for diversity.
