Uh, it's a little difficult. The main thing seems to be the pattern for the cuff. What about finding a basic sock pattern for toddlers that has the same number/multiple of the tulip-pattern stitches to allow you to do the tiny-tulips pattern - and use that? From the heel on down, should be pretty basic.
And I don't see what size needles are called for in your adult-sized sock pattern. But even so, adapting this one on down to tiny-toddler-tulips would be kind of like, uh, rugged.
Hope this helps,
