Knitted sweater for a boy

I have been knitting alot over the years. This is one sweater I knitted for my youngest son, when he was 5 years old. When I knit for children, I always try to knit the sleeves without any patterns, because the children are not so happy getting there fingers stuck in the yarn.
The yarn I have knitted this sweater with, is called Unique and it is 100% wool from Shetland.
