My 3 yo (newly 3...as in 3 years and 2 days) went for his well-child check today with my dh. He was deemed healthy in every regard, but one thing bothered me. She (the doc) asked my son to draw an x for her on a piece of paper. He did so without a problem, but my dh said the doctor said "he did it, but he has an immature grip". My dh made the point that he is only 3! He loves to draw and write, but primarily uses beeswax blocks to do both. Occaisonally he uses markers and pencils and his grip looks fine to me. We are both teachers (I'm a primary teacher) and I feel pretty experienced in early childhood development, but this threw me for a loop. He can string beads, do puzzles, feed and dress himself, and do plenty of fine motor tasks. Does anyone think this is anything to worry about?
