I’m on vacation for 3 weeks and didn’t bring my book. Can someone tell me when a baby drops things on purpose, and what is average, superb, slow? I think it’s in the chart in the books. Or maybe I’m remembering wrong… Thanks!
It is not on the chart.
“Vital release” is 1 month (superior), 2.5 months (average) and 5 months (slow). The next stage is “Prehensile grasp” at 3.5, 7 and 14 months. After that is “Cortical opposition” (AKA pincer grasp) at 6, 12 and 24 months.
Voluntary release, I think, develops with the prehensile grasp, or shortly after. I don’t ever remember Zed picking things up and not dropping them at will.
HTH
Thanks so much, that’s perfect!
