why it matters
Rest reduces the stream of new demands on a child’s attention. The strongest evidence concerns sleep, naps and short periods of wakeful rest: naps can support memory consolidation in early childhood, while research suggests that quiet wakeful rest after learning may help new memories settle.
The emphasis should be on rest, reduced stimulation and unstructured pauses, even allowing for boredom. Research source: wakeful-rest systematic review and early-childhood nap meta-analysis
