that is kind of odd for her to go on a cricket strike at such a young age. My breeder told me not to offer any type of worm until about 5 1/2- 6 months due to the fact that alot of them prefer worms over the crickets. My cham stopped eating crickets at abvout 7 months and mostly east a variety of worms, supers, wax, horn, silks, phoenix. He will eat them all! Try not offering the meals and do the crickets only, but do not starve the baby! Some people hold off on feeding their chams to try to starve them into eating crickets. Maybe as an adult but I would not suggest doing that as a baby. They need to eat, eat eat!!
