While a dragons diet isn't an exact science since all beardies are different in their own way, some will love their veggies while some will never ever go close to them. This is just the nature of all living things. This is a guideline as to what the average dragon should have. My male (Benoit) never ate veggies other the the odd mango, apple or peas, but in very small amounts and only once in a blue moon.

Since juveniles are growing, they require more proteins to help build muscle and bone. While dragons never really stop growing, one they hit 12 months, the rate of growth is very slow. My male (Benoit) was 18.5 inches long between 1 - 4 years, then when I measured him again at 5 years, he was 19 inches long. For beardies under 1 month, you will want to get pin-head crickets, since babies are very small you need extremely small and soft crickets as protein.

Some thoughts 

Dubia Roaches*

 5

High protein, low/soft chitin, staple food 

Crickets

 4.5

Staple protein, soft chitin, indigestible heads 

Super worms

 3

Hard chitin, highly addictive 

Meal worms

1

Extremely hard chitin, not very nutritious

Butter worms

2.5

No chitin, high in fat, good when brumating

Silk worms

5

No chitin, high nutrition, excellent hydration

Wax worms

2

No chitin, high in fat, good when brumating

Horn worms

4

No chitin, no real nutrition, very high hydration

*illegal in Canada
Chitin is the hard protective armour most insects have.

*Spinach is very bad as it binds to calcium. This means that the calcium you are sprinkling on the salad and on the protein is getting taken away from the Bearded Dragon, including the calcium already metabolized in their bones and muscles. The loss of calcium will bring on the disease called Metabolic Bone Disease(more on MBD in the Diseases section).
