Yes, it's normal. Don't worry about it! And when she loses interest, and she will, let it go. At this age, she's far too young to be expected to do it from now on. More important is all the reading you are doing with her, talking, giving her vocabulary, giving her manipulatives to work those little hand muscles, these kinds of things. Give her play-doh, clay, have her make necklaces out of beads because those little finger movements are so important for being able to effectively write later. Let her color with crayons, teach her to cut with scissors. All this will get her ready for kindergarten. The writing will come out of all of this.
