she needs some fattening up so she can have as many crickets as she will eat in about 15 minutes time. she probably is hungrier than normal right now. you can dust the crickets every time with the leo dust if you feed them less than 3 times per week, every other time or so if you feed them more.

you might need to show her the mealworm dish. since she is so small she may just not know they are there, not really being able to see them without climbing into the dish. prop her up on it and drop in a few worms so she can get a good view of them crawling around in there. sometimes with hatchlings i have had to drop a mealworm on the floor of the enclosure in front of the leo to get them eating the mealworms. i'll drop in about 4 or so, one at a time, waiting until the first one is eaten before dropping in another. i usually only have to do this a few times before they figure out that they are yummy and that they can just go to their dish and get them for themselves.

for now i'd give her crickets every other day and try getting her to eat mealworms on the in between days. once you know she is eating the mealworms you can scale back on the crickets.
