Notice the look of intense concentration.
With her walking toy, Staley will walk across the living room (about 6-7 feet) with someone keeping her walking toy from getting away from her. She's not a speed walker and she occasionally steps on her own feet or stops to wave at the cats, but she loves to practice. And although as an occupational therapist, I should probably insist on equal practice time for her crawling and pulling to stand, when Staley looks at her stroller, signs 'more', and says 'up', I just can't help myself. I guess proud mom trumps practical therapist this time.
