    32 weeks
  31. At this infant stage, the radial-digital grasp develops
    36 weeks
  32. At this infant stage, the inferior pincer graso develops and the beginning of voluntary release.

    44 weeks
  34. At this infant stage, superior-forefinger grasp develops, with wrist extended and deviated to ulnar side; smooth release for large objects and awkward for small objects
