If you can start feeding him 3 times a day rather than two, you'll want to do that till hes 4 or so months. What i do for beardies around that age is feed them at 7, usually i throw in crickets once i turn the lights on so they can chase them around later. Then around 12, or 3 pm i clean out the other crickets and see how many they ate and put in some again, and then around 6 or so i do the same thing and then at 9 pm the lights go off. Make sure no crickets are inside by then or they could bite your baby.
If this helps
This is what i go by for feeding,
1-4 months 3 times a day 10-20 bugs each feeding,
4-12 months twice a day 10-20 bugs each feeding,
12-20 months once a day 10-20 bugs each feeding,
And then 20+ months every other day 10-20 bugs each feeding.
And of course daily salads in all age ranges, usually collard greens, mustard greens, turnip greens daily and then the occasional blueberry, banana, or red raspberry once or twice a week in their salad.
As for the bug portion i usually feed crickets, calciworms, dubia roaches, and turkish roaches for staples.
As for dusting, ones below 20+ months usually 5 times a week for calcium and 2 times a week for multivitamins. And then for the 20+ month olds usually 3 times a week for calcium and once a week for multivitamins.
As for treats i occasionally will give them hornworms, superworms or mealworms. Usually 5-10 mealworms, and then for hornworms and superworms 2-4. For mealworms i offer those once or twice a week and then with superworms and hornworms usually once a week or twice every two weeks. Hornworms can be offered a bit more than superworms can since they do have less fat and are mostly just moisture which is good for
hydration in some cases but can cause diarrhea if given too many. I dont recommend you giving him superworms or mealworms at the age he is.
Also how small is the tank and is the heat lamp the only light?
