Like was said by the other poster, babies usually won't eat their greens. Just don't offer the mealies anymore. Too much of a risk. Keep offering plenty of extra small crickets every day. Offer a finely diced salad of greens or even try the spring mix that comes in a bag since it has more colors. It does have a decent amount of calcium in it. It's about equal to the amount in turnip greens but tastes better to babies. Offer the salad in the morning/early afternoon. Then offer the crickets in late afternoon.

This is the best way to encourage him to start eating his greens. Eventually he will have some. As he gets older he will eat more and more of it.

It's ok if he doesn't eat any right now. Babies eat mostly insects anyway. After his first year he will simply not want as many insects and will eat a bowl or 2 of salad every day.

My dragon is over 2 years old now. He hates crickets now. He only gets super worms, silk worms, or horn worms a couple times a week. He eats a big bowl of greens every day though. If I put 6 worms in a bowl for him he will only eat a few and leave the rest for the next day.

Babies eat about 90% protein (insects) but its the opposite for adults. No worries. Just fatten him up with his calcium dusted crickets. Use plain calcium too. Not the kind with D3. This is dangerous for them.

Oh and no spinach! Spinach blocks the bodies ability to absorb calcium. Just greens, spring mix, and diced fruits n veggies. No citrus.

In the summer if they grow by you pick him some yellow dandelion flowers and leaves as well. These are nutritious for them and they love them! And clover leaves and their purple and white flowers.
