A sock for M's sandal

I've been wanting to crochet M some socks since I found this cute and inexpensive sock yarn, Bernat sox and since my sis made him some. . .but I couldn't find a pattern that I liked. I finally found one and made this sock, then I promply got sick and have yet to finish the mate.
In the first picture you can see that like shoes he's trying to remove this sock so I put on the sandals that he cannot remove over them, hence the second and third pictures. He's wearing one of the tickle turdle crochet wool diaper wrap covers that I made for him too!
