Really getting scared for my month old leopard gecko SKINNY!!?

We have had all our lizards since they were VERY small, they DO go through a skinny phase but they do bulk up in time. just keep checking out that he eats and poops. get small crickets and sprinkle the calcium powder ON them. make sure you are using the leopard gecko powder!!! each powder has diffrent things for diffrent pets. also get the gel cricket food. what the cricket eats, the gecko eats! i woun't give him the wax worms this young, wait a few months for him to get a better digestion. you wouldn't feed a baby human pizza would you? =) hope this helps!
