&gt; My main objection to pushing STEM down to the diaper set is that it all seems to involve screen-based learning tools, and I am sure that little ones don’t need more screen time.<p>This thing seems pretty cool. On the whole, we probably need to have more of an awareness of how important tactile and spatial factors are in child development. But the top selling point, according to this reviewer, is that it protects your child from the &quot;screen time&quot; bogeyman? Spare me.
