What's your hurry? He's not behind or delayed!!! Having his name "all over the place" is awesome! Just encourage him with what he's already doing. If you ask teachers, they don't care a whit if kids can write when they come to kindergarten! They just need to know how to sit in a group, negotiate their own space without hitting, and be able to separate from Mom & Dad. That's all. He'll figure it out in time. For now, if you provide lots of opportunities to develop fine motor skills (coloring, small blocks like Legos, craft activities), then he will have the dexterity to handle a pencil and learn along with the rest of the kids.
I really think we push our kids way too much in so many ways - tons of scheduled activities for "enrichment" and structured academics at home or at "academic" preschools. Kids have forgotten how to be kids and how to play freely and creatively. They need down time to let their brains develop. They need to have pick-up games with kids in the neighborhood, ride bikes, dig worms, catch toads, blow dandelions, chase fireflies. They need to combine parts of different sets of toys into new structures. My advice, based on so many conversations with teachers, is NOT to worry about taking academic pursuits into your own hands. Instead, take nature walks and go to museums and just let your child DISCOVER. You will both enjoy it more, and it will pay off in the long run! My kid was late to write, still holds a pencil "wrong", potty trained late, and only was allowed two structured activities per week, one of which was religious school and the other of which was usually a sport or an after school club. By high school, he was ready for the track team every day. He's a strong leader, got into a great college with a big scholarship even though he wasn't a straight A student, became a champion runner, was team captain, has great friends and never got into any trouble. He's pursuing an environmental engineering degree and he gets along with all kinds of people and can function in all kinds of social situations. I'm glad we did it the way we did.
