It took me a while to figure out how to get the pattern together, probably because I couldnt "picture it" in my head to see how the bits would fit together.
I made the 2-3yrs with hood for my girl who is average size, and 3 at the end of next month. The ribbing was only just long enough, and it seems quite firm under her arms when the hood is up. The hood could probably be a bit bigger. I will also do one for my 8yo girl and get her opinion on the fit.
