She needs a lot more than you are feeding her if she is young. My adults eat more than two or three insects a day. At her age, she should eat all she wants. Make sure the insects are small enough.
Go to this thread, Message #9, and look at the pictures of this baby on the scale eating a silkworm.

This is one of the babies I raised. You can see how big that silkworm is. Before he left my house a few days ago, he would eat 5 or 6 that size plus all the crickets he wanted. You can see, he isn't fat.
At some point, you will probably want to cut down on her food intake but not now when she is so small and growing. Make sure you lightly dust all the feeders with powdered calcium without D3 right before you feed them.
Please go to the Health section and fill out a "How to Ask for Help" form because I think you can use some guidance from some experienced keepers..
