Hi A., I'm a pediatric occupational therapist. The last 13 years I worked in the school district with children with fine motor and writing delays. At 3 years old, I'd be really careful to not push him too hard yet. He is still developing his hand dominance, which often times is not really established til closer to 4 or 5 yrs. old. Right now, I'd suggest giving him "bilateral tasks", fine motor acivities that requires the use of two hands working together (i.e. stringing beads, roller pin with playdough,...). Have him do fine moter tasks that require a "tripod grasp" (using thumb, index and middle finger together). A marker board hung up on a wall with fat markers will exercise his shoulders and upper arms, needed for stability for fine motor development. Upright visual stimulation will also help with visual discrimination for combining verticle, horizontal and diagonal lines for letter formation. Hope that this helps. S.
