I decided to dress my 12 month old son, Jason, as a zombie after watching him walk around at Magic Mountain Fright Fest and noticing that he walked just like a little zombie ( he has only been walking for a few weeks).  Not only did he walk like a zombie, but he was growling at people just like a little zombie (he is such a goof)!  So my mother and I designed the cutest Zombie baby ever (I wanted it to look old and babyish so we went with knickers). She sewed it, and my little zombie baby was born!!
