Mine get crickets once or twice a week depending on availability, and gargoyle gecko diet any day that they miss out on crickets. I dust the crickets with calcium about 2/3rds of the time and herp vitamins other times. I feed CGD generally 4 days a week and add a small amount of baby food for flavor about half the time, but they willingly eat it plain after being trained to it. Every now and again (every two weeks or so), I'll give a little bit of plain fruit or a different kind of bug as a treat.
I don't have babies yet, but when Scooby and Waldo were still little (the others came to me big), I fed them every day with crickets 2-3 times a week and alternating between CGD and GGD with a little fruit mixed in the other days. My routine has changed a little from time to time, but it's never been significantly different from this.
