It's pretty easy. All you have to do is get some powder calcium or liquid calcium and put it on most of the foods she eats. With the crickets, put them in a bag and add some powder calcium in it. Then shake it up so that the crickets get covered, "frosted", with calcium, then feed them to her. With the liquid calcium, you can put drops of it on basically anything she eats. Even of she isn't pregnant, this is good for her.
