Is it safe for a 5 year old to wear the patch (Daytrana) and is it safe to cut the patch in half to reduce the dose?

I have just posted an article on preschoolers and ADHD:

Most research in preschoolers is with methylphenidate even though it is only FDA approved down to the age of 6.  The patch works fine if cut in half.  Be aware that after six weeks of daily use blood levels may go up and the dose may need to be reduced further.
