Hey yes it's me again ; ). I am still worried about my gecko

. I have now had him about a month and a half. He hasnt eaten a cricket or mealwrom since i got him. I have to literally pick him up and put baby food in his mouth, all he will eat is baby food. Also to, i think he is getting skinny but it is hard to tell when u see them everday. Is it normal for when u hold him for, under his head where u can see him gulping, is it normal for it to go really really skinny one minute and then go huge like it i gonig to explode the next?
