gee, 2 crickets a day is a small amount, but it sounds like you are doing everything else right. Most of my hatchlings will eat 2 or 3 crickets for the first couple days but by a week they are eating 4 or 5 or more a day. I have recently started feeding mealies as well so I'm not sure how much they are eating but they sure are growing alot faster with their constant supply of mealies and occasional crickets.

I leave the mealies in a dish and check on them every night or every other night at the least and pull out any roaming mealies or refill the dish. My older geckos that were only on crickets for there first 3 months are the same size as some of my one month olds that have been on both crickets and mealies for the month. lol. Crazy!! Anyway, I hope she starts eating more soon. Try making it hard for the crickets to hide and see if that helps. But as long as she is eating and growing, even if it is slow, I wouldn't worry too much at this point she is still very young.
