A proper adult crested gecko diet should consist of cgd mixed with water two to three times a week. I would avoid mealworms all together, and possibly only feed crickets once a month.
To explain in detail on the points above..
Mealworms hold very little nutritional value to any reptile. But they are cheap to produce, so much like heat rocks and the like, you will be told they are a good staple. Pheonix Worms, Butter Worms, and even wax worms have better nutritional value, as well as no hard exoskeleton that they can't digest.
I have kept all of the readily available Rhacs over the years, and have for the most part cut out insects all together when feeding them. Leachianus nearly never eat insects, even as babies. Sarasinorium and Cresteds will accept them as babies, but will begin to leave them alone at around 8 months to a year old. Chahoua will eat insects throughout their life happily, as will Gargoyles. Cgd is a Full Meal Replacement, meaning it needs no supplemental feeding.
Finally, the baby food issue. You have to remember that no matter the brand, baby food is exactly that, food for a human baby. It contains many things which the gecko can not easily digest. The excess sugars can also lead to obesity.
Cresties do tend to get stuck on the baby food mixture though. It's sweeter. Plain and simple. I would suggest to remove it from their diet by one of two means. Either slowly use less baby food, and more water every time you feed until the baby food is out of the equation entirely, or instead of baby food, mash up some real fruit, and mix that in. Mangos, papaya, and other soft non citrus fruit make great choices. I usually give these mashed fruits as a treat once a month to most of my fruit eaters either way. They tend to devour it.
