3/4 of an inch is too big for your toad even without the legs. The food shouldn't be any longer than the space between her eyes. My toads that size eat fruit flies, they probably eat 20 each and 1 or 2 tiny pieces of worms...the worm pieces are less than 1/4 inch. They COULD probably eat 1/4 inch crickets, but I haven't ventured there yet. Have you gone to your pet store to look at crickets yet? She probably would have no issues taking down small crickets or fruit flies. As young as she is, she should be eating something daily. If you haven't been to the pet store, I would get there soon, she also needs calcium and vitamin dust, or you risk stunting her growth because she doesn't have the proper nutrition.
If you really can't get to the store soon, go outside and find some small roly poly bugs (the adult shells are hard to digest) because they are loaded with calcium. I've also had luck feeding one of my picky eater toads those little green leaf hoppers. I'm not sure how healthy those are for them, but I was desperate because I have a small skinny toad that was refusing to eat fruit flies. She perked up hugely after eating a couple of those. She is back on the flies now and is doing well.
