If you were feeding roaches to the adult, do you have a colony established? If so, just feed them the baby roaches. Roaches are most likely on the regular menu for these guys in the wild (and probably make up a large portion of their diet), based upon where they originate.
If you don't have baby roaches or you still want to feed crickets, I actually do have a tip for you (forgive me for not remembering sooner!). If you put the crickets into a bowl (one you would eat out of) with really smooth sides, they cannot escape, but they will try very hard, scrambling about and making alot of movement (thus attracting the lizards). I use a
Corelle brand bowl for this, I find they work better than some others. I had been doing this for my CWD, who was off her feed. It kept the crickets where she could see them and get to them, without me having to forcer her to eat (open mouth, insert cricket style... a real pain, and stressful to the lizard). You might think the crickets would just jump out of the bowl, but IME they cannot get enough purchase on the surface of the bowl to jump. I hope this helps!
Definitely offer roaches as well if you have any small enough!
