Reading and writing are sophisticated skills for a young child. But there are some things you can do to encourage your son's interest in both. Read to him nightly. If you don't have a supply of books in your home, visit the public library in your city or county and check some out. It's a good place to encourage your child to pick out books of interest to him as well as a few selections by you. Reading together nightly, in my opinion, is the No. 1 tool to encourage a younster to read.
To encourage writing, provide blank paper and thick crayons or colored markers. Consider establishing some coloring time as you fix dinner. This provides you time to talk together, as well as giving your son an opportuniity to share his writing skills.
Don't be too conscerned at this point. But if you feel your son is behind the other students who are in his age-group, consider calling your local school district and asking to participate in their "Child Find" programs. This is a service to preschool children and their families, whch assesses a child's strengths and weaknesses and makes recommendations to families IF there is a developmental concern. The professionals who work with young children are usually quite friendly and skilled. I've included a web site that gives some general information about this service nationally, but each state administers their programs a bit differently.
Enjoy your son as you "read" and "write" together!
It's normal for preschoolers to still be learning the basics of reading and writing, so don't worry too much. There are many fun ways to encourage writing at home, as well as to make learning fun. Here's a great articles on "How to Practice Preschool Letter and Name Writing." Hope this helps!
I have a Kindergartener who has "fine motor deficits" (difficulties manipulating scissors, holding pencils/crayons, writing, etc...). I have him practice writing letters using a dry-erase marker board. You can also buy paper that has the letters he/she can trace (the letters are outlined with faint dots). Good luck! I'm having a heck of a time myself!
Pre school children need lots of fun ways to learn their letters other than workbooks. It would be helpful to know how old your son is as many children are not interested in letters until they are in pre k class. Encourage letter recognition before writing the letters. Look for letters in his name in signs you see or books you read to him. Try making the letters in his name with shaving cream, finger painting, twisting pipe cleaners into letters. Have him imitate you and then try it on his own if he is old enough to do so. A good series of books by Illg and Ames can help you determine what is expected of him at his age.

It's hard for preschoolers to want to write due to the muscles in their hands and fine motor skills have not quiet developed yet. Do not get discouraged, I've been through this too, and actually struggling with it again now. It's helpful to do activities that will strengthen the muscles in the hands so they don't get so tired and they do start to ache after just a short while.
Some helpful activities are:
Twisting bolts over screws (supervised, of course)
Threading things, like pasta noodles on thread
Popping bubble in the bubble packaging wrappers
I found using a chalkboard helped, they just love it
Pinching items between their fingers, like picking up pennies with a pair of tweezers, you can also find games like this
There is a good activity on education.com that I've used, you cook spaghetti noodles and then allow your child to make pictures using the noodles, it is challenging for small hands to maneuver the noodles around-link provided.
Just have fun, relax, I promise, they'll get it. Best Wishes!
