Darling. I modified it a bit to make it more like a size 2-3 toddler. That is easy to do in this pattern: Cast on for the largest size adding stitches in multiples of 4. I added 4. Knit as directed making the raglan increases until you have the size you want. If you are unsure what the measurement should be, you can measure it up against a sweater whose fit you like, or use this site to find the standard child/youth measurements for sweaters.
