The ups and downs of sock knitting

First the "ups." I finished these socks for my 4 year old daughter! She loves them and would wear them every day if I let her. They are made with Knitpicks simple stripes in 'snapdragon.'
Now for the 'downs.' Remember my Trekking sock I am working on? Last weekend I was able to get a lot of knitting time in and I managed to get the first sock up to the point of shaping the tow. I got up the next morning to find that my three year old had decided to "knit!" He had taken out the needles and unraveled the sock! Almost all of it by the time I caught him!!!!!! I could cry!
