You really need to try and convince your mom to allow crickets if you're going to have a frog, especially tree frogs as they live off gut filling bugs such as crickets. I'm not 100% sure what else they can eat but I'm guessing if she's not allowing you to have crickets, she's not allowing you to have any other bags, am I correct? I hope you manage to convince her in the end because you can hide them away from her so she won't become so scared when she walks in your room or whatever and they're safe in the prepack box they come in or a cricket pen. Good luck anyway and let us know if you convince her.
