He will get big pretty quick. What size is the tank? How old is your baby? Also i would make a couple changes to the tank. Do not have a water bowl, as chams don't drink from water bowls, they drink when you spray them and from water dripping on a plant. If you need a dish to catch the water that is ok but be really sure it has a screen over it. Your cham can drown in very little water. If you are going to cup feed get a cup that is small enough the cham can get to the crickets easily, and make sure the cup isn't something the cham will fall in and not be able to get out of. If you free range crickets for him, try to make sure there are no live crickets left in his tank when he sleeps. Crickets will often chew on sleeping chams. Last monitor temps very closely. A glass cage can overheat quickly.
