After the success of the larger mechanical dolls like Baby First Step, Swingy, and Dancerina, they started making similarly styled dolls in miniature.  

This is Baby Small Walk.  She is just 11" tall.  She loosely resembles the later version of Baby First Step, although her dress more closely resembles that of Swingy.  Unfortunately I have been unable to get her to work so am not exactly sure how she actually walks.  If she is anything like the larger dolls, I bet she is quite a kick!
