My K'er has always picked up Language Arts very well. We've worked on penmanship and letter formation since he was 31/2. We started with Hooked on Handwriting and then Horizons Preschool, now Horizons Kinderarten. So he's been "writing" awhile and has not had any problems. I have noticed for the past two weeks or so that his grip on his pencil is slipping. His thumb is starting to shift over his index finger. We have tried different grips and always the same thing. THis is a new thing, and I called him on it today, which led to frustration and tears. He is 4 1/2, will be 5 late summer. I know not to stress over little things, but I don't want this to become a bad habit that will be much harder to break later on. We tried putting a star where the thumb goes. He always positions the grip correctly, but we used the star as a way of reminding him to keep his thumb there. Well, after syaing "thumb goes on the star" about 26 times, we were very "done" with that. Any suggestions, or will "this too shall pass"?
