Honestly, baby emperors will eat their selves to death.. So yes, you are feeding that little one way too much. Give it a week off please or you will kill it. I have 8 little ones left from a litter of 15 my big girl gave me in march of 2011. (I sold the rest) they are only fed 3-4 times a month and they get enough crickets to get nice and fat each time.
If it is still that plump in a week, wait another week. Mine have gone up to 3 weeks before during the winter. Keep the humidity up in the enclosure and give it time to digest that belly full.
