Apparently he didn't want his arm in his PJs anymore. My friend, Courtney, said she would put her son, Nash, to bed and in the morning they would go in to find him naked. You know, I saw Nash talking to Mason at Nash's birthday party... okay Courtney - if Nash gave Mason any ideas - I'm coming after you ;-) But seriously, the boy loves to be naked. (notice no shirt in the pics below).
Mason is also still loving his blanket. He is still a blanket sucker. I don't know if it is much better than the thumb - but I do take the blanket away during the day. He is only allowed to have it during naps and bedtime.
