Are you trying to hand feed? Do you have appropriately sized food? Have you found any stool in the enclosure?
Do not try to hand feed--it is just too frightening.. Put the feeders (live appropriately sized crickets) in the cage free.
You need to fill out the form at the top of the Health section. It is basically a questionnaire on how you keep your chameleon from lights, temperatures to enclosure, food, stool and supplements. Pictures also really help, both pictures of the chameleon and the set up.
This is a really long time for a baby to go without food. I think a vet visit is in order.
Not eating can start a downward spiral.
