>>Anyway, should I just stop crickets all together and just feed her the gecko diet?

yes. and ditch the baby food too, it's not healthy and will mess up the nutritional value of the CGD. i doubt she is sick, some geckos just lose interest in crickets at a certain age, my gargoyle did the same thing. every other day is an awful lot of crickets. when feeding CGD, crickets should only be offered once a week a few at a time, if at all. they are not necessary, and she's probably past her growing stage.
