In addition to above
Feeding assistance :
It is easy to handfeed/force feed a little beardie.
Crickets are dead easy to use - I simply take a few crickets out of the dusting tub at a time, disable them (crush their heads) and place the little lizard on my tummy/chest facing me, I then pull a hopper leg off, the drumstick end (fat end of the leg) is then pushed between the lips on the side of the mouth , beardie starts to chew it, and quickly while he's chewing I squeeze some cricket goo out and place firmly but gently the gooy end of the cricket against the lips, chances are the beardie will eat it when it tastes the gooy stuff.
repeat

Other techniques / options :
>>>> folded plastic coated playing card technique - self explainatory , fold card , cut hole big enough for food item to go through hole in middle of crease, slip folded card between lips and plies mouth open using card as two levers, while mouth is open pop a food item in through the hole, remove card , lizard eats food item .
repeat.
>>>> make an insect puree/mash , and give via a syringe with a large bore needle hole.
>>>> try Grup Pie (Rapashi)
https://www.youtube.com/watch?v=awk__AanmP4 I've not used this product but know of at least one keeper who uses it as a staple for his beardie and reckons it's great.
>>>> try a different feeder ( CalciGents aka BSF maggots aka phoenix worms ) , silkworms.
Other things to consider are :
>>> how long the lights are on each day , if too short he'll think it's winter , suggest lights on 15 -16 hrs per day for a young beardie.
>>> temperatures
>>> is the UV light suitable for a beardie (must be rated at least 10% UVB and provide significant UVA (about 30%) and be positioned so the beardie can get close enough to experience extreme levels of UVA and UVB (equiv UVI about 13-14).
>>> feeding schedule (when and what)
