Its amazing to me what will entertain a little one.  Emma was having so much fun playing in a box. I think a plain card board box is one of the best toys for  children.  They all seem to love to play in them.  Its always so fun to see what adventures they will have with just a plain old card board box.  "M" was using this one as a bed for her and her doll.  Oh the joy of being a kid.
