Handwriting Suggestions??

I've never really been concerned about Robbie and writing. He's still very young and I have been told so many times that boys write later and apparently with less endurance than girls. For these reasons, it's never been a biggie on my to-do list.

For months now, Robbie has been nearly obsessed with writing words. He still enjoys spelling words with our letter tiles, but he "writes" all the time. He used to do his Explode the Code books orally (he'd circle or "x" the answer when that was called for). Now, he wants to try to write every word. He doesn't care how long it takes, he wants to write.

He doesn't form some of his letters correctly, and I want to make sure that (since he insists on writing letters and numbers) he learns the right way from the start.

I've been flip-flopping on how to teach him this. I've considered Kumon books, Handwriting Without Tears, special books for lefties (he's been an obvious lefty since before he was a year old, but we've never pushed either hand) as well as several others. None of these really appeal to either of us.

He's interested in both print and cursive (I had always planned to simply wait and teach cursive first when we tackled this). A friend of mine suggested simply teaching him myself using both print and cursive. I've been wondering if this could actually work. Would he get confused? Would I have him learn print and simply become familiar with cursive as he goes? Would it be better to use the print as reference and teach the actual writing with cursive? Should I scrap the idea altogether?

I guess I'm asking for any opinions or advice? These plans would officially be for this fall (official Pre-K). We have the Startwrite 5.0 software, so I can make sheets myself. What would you do if you were in my shoes? Perhaps some of you are wondering the same thing. Who knows?
